DotNetNuke website migration to Azure fails with nx domain DNS error - asp.net

I am currently working on a DotNetNuke website (07.03.02) and I am trying to migrate it to Azure. The website is working on my local machine with IIS.
I followed this tutorial to migrate the website : http://www.dnnsoftware.com/community-blog/cid/154975/moving-a-dnn-install-to-microsoft-azure-websites
So I created a new web application on Azure that will host the website files. I also created a new database on Azure, and I imported my DNN backup database.
I changed the connection strings in my web.config to use my Azure database, I uploaded the website folder on Azure.
Now if I try to browse my webapp using the link [sitename].azurewebsites.net, I get the following error :
DNN Error Domain Name Does Not Exist In The Database
DotNetNuke supports multiple websites from a single database/codebase.
It accomplishes this by converting the URL of the client browser
Request to a valid PortalID in the Portals database table. The
following steps describe the process:
Web Server Processing When a web server receives a Request from a
client browser, it compares the file name extension on the target URL
resource to its Application Extension Mappings defined in IIS. Based
on the corresponding match, IIS then sends the Request to the defined
Executable Path ( aspnet_asapi.dll in the case of ASP.NET Requests ).
The aspnet_isapi.dll engine processes the Request in an ordered series
of events beginning with Application_BeginRequest.
HttpModule.URLRewrite OnBeginRequest ( UrlRewriteModule.vb ) The
Request URL is parsed based on the "/" character A Domain Name is
constructed using each of the relevant parsed URL segments.
Examples:
URL: http://www.exemple.com/default.aspx = Domain Name: www.exemple.com
URL: http://209.75.24.131/default.aspx = Domain Name: 209.75.24.131
URL: http://localhost/DotNetNuke/default.aspx = Domain Name:
localhost/DotNetNuke URL:
http://www.exemple.com/virtualdirectory/default.aspx = Domain Name:
www.exemple.com/virtualdirectory URL:
http://www.exemple.com/directory/default.aspx = Domain Name:
www.exemple.com/directory
Using the Domain Name, the application queries the database ( Portals
table - PortalAlias field ) to locate a matching record.
Note: If there are multiple URLs which correspond to the same website
then the website alias field must contain each valid Domain Name in a
comma separated list.
Example:
URL: http://localhost/DotNetNuke/default.aspx URL:
http://MACHINENAME/DotNetNuke/default.aspx URL:
http://209.32.134.65/DotNetNuke/default.aspx PortalAlias:
localhost/DotNetNuke,MACHINENAME/DotNetNuke,209.32.134.65/DotNetNuke
Note: If you are installing the application to a remote server you
must modify the PortalAlias field value for the default record in the
Portals table according to the rules defined above.
So I inserted the Site Alias ([sitename].azurewebsites.net) record into the PortalAlias table as mentioned in the turorial.
Now when I try to reach the website [sitename].azurewebsites.net, I don't have the previous DNN error but it loads for a long time and then I got the following error :
www.[sitename].azurewebsites.net’s server DNS address could not be
found. DNS_PROBE_FINISHED_NXDOMAIN
After the load end, the URL curiously become https://www.[sitename].azurewebsites.net and the DNS error occur.
Is there something I need to change in Azure or in my web.config file ? Maybe there is something to configure in DotNetNuke or in the ASP version?
I don't get why my browser change the url and why this dns error occur (I have no issues with my local IIS server).
(I also tried by using the automatic portal alias transfer as mentioned in the tutorial but I got the same result : the alias is inserted in the database but I still have the NXdomain error)
Thank you for your help !
Etienne.

In your original post you have:
www.[sitename].azurewebsites.net’s server DNS address could not be found. DNS_PROBE_FINISHED_NXDOMAIN
Try to manually put the . (The full, http with colons, etc.) Sometimes the web browser will add the WWW automatically, thinking you wanted it (I hate when they do that). Azure doesn't know about the www subdomain, so that is why you are probably getting that error.
Edit: Oh, and the long load time is good - it means that azure compiled your site and you didn't get a compile error.

The fact that you get an error that comes from DNN is good news, and means that you have (probably) done the major work correctly.
Now, you need to get into your database and modify the PortalAlias table so that there is an alias for sitename.azurewebsites.net. (I'm assuming that the brackets around sitename are incorrect and "[sitename]" eeds to be replaced by the actual domain name for your site.)

Stuck with woocommerce_rest_authentication_error: Invalid signature - provided signature does not match

Below issue was posted by me on https://github.com/XiaoFaye/WooCommerce.NET/issues/414 but since this may not be related at all to WooCommerce.Net but on a lowerlevel to Apache/Word/WooCommerc itself I am posting the same question here
I am really stuck with the famous error:
WebException: {"code":"woocommerce_rest_authentication_error","message":"Invalid signature - provided signature does not match.","data":{"status":401}}
FYI:
I have two wordpress instance running. One on my local machine and one on a remote server. The remote server is, as my local machine, in our company's LAN
I am running WAMP on both machines to run Apache and host Wordpress on port 80
The error ONLY occurs when trying to call the Rest api on the remote server. Connecting to the local rest api, the Rest Api/WooCommerceNet is working like a charm :-)
From my local browser I can login to the remote WooCommerce instance without any problem
On the remote server I have defined WP_SITEURL as 'http://[ip address]/webshop/ and WP_HOME as 'http://[ip address]/webshopin wp-config.php
Calling the api url (http://[ip address]/webshop/wp-json/wc/v3/) from my local browser works OK. I get the normal JSON response
Authentication is done through the WooCommerce.Net wrapper which only requires a consumer key, consumer secret and the api url. I am sure I am using the right consumer key and secret and the proper api url http://[ip address]/webshop/wp-json/wc/v3/ (see previous bullet)
I already played around with the authorizedHeader variable (true/false) when instantiating a WooCommerce RestApi but this has no effect
Is there anybody that can point me into the direction of a solution?
Your help will be much appreciated!
In my case, the problem was in my url adress. The URL Adress had two // begin wp-json
Url Before the solution: http://localhost:8080/wordpress//wp-json/wc/v3/
URL Now, and works ok: http://localhost:8080/wordpress/wp-json/wc/v3/
I use with this sentence.
RestAPI rest = new RestAPI(cUrlApi, Funciones.CK, Funciones.CS,false);
WCObject wc = new WCObject(rest);
var lstWooCategorias = await wc.Category.GetAll();
I hope my answer helps you.
Had the same issue. My fault was to define my url incorrect: http:// instead of https://.

The authentication endpoint Kerberos was not found on the configured Secure Token Service

I've encountered a challenge regarding internet-facing deployment installation for CRM using a AD FS server. After the setup is complete, users are able to access the CRM server - but when trying to run custom pages the following error message is prompted:
"The authentication endpoint Kerberos was not found on the configured Secure Token Service!"
I've found several solutions on the internet for this issue:
First I found a KB article from Microsoft providing a possible
solution, this involves updating MEX endpoints by running a provided
PowerShell script.
(https://support.microsoft.com/en-us/help/2828015/configuring-ad-fs-2.1-with-microsoft-dynamics-crm-2011).
But this doesn't seem to be the issue.
Another solution could be to update the CRM rollup version (currently have version 14 installed, latest is version 18) - this is something that I want to avoid as it might lead to further issues.
Have anybody else encountered a similar issue, and in that case how did you solve it?
I have just spent last few days to figure this exact same error message and it turned out that it was the "Domain" attribute in crm connection string. Copied my answer to my own question at the Microsoft Dynamics CRM community forum here:
"Well, I found the culprit - it was the Domain attribute in the connection string:
For connecting from outside the domain, it does not like to have a Domain in the connection string:
Connection string format 1 (without Domain attribute): "Authentication Type=Passport;Server=https://devcrm.myco.com;Username=devuser#myco.com;Password=pwd" - this works both inside and outside the domain "myco.com"
Connection string format 2 (with Domain attribute): "Authentication Type=Passport;Server=https://devcrm.myco.com;Domain=myco;Username=devuser#myco.com;Password=pwd" - this only works inside the domain myco.com but NOT outside (exception: The authentication endpoint Kerberos was not found on the configured Secure Token Service!)

The key is in the Xrm.Client.CrmConnection.ClientCredential:
If Domain is NOT specified in the connection string, when connecting from outside domain, Xrm.Client.CrmConnection.ClientCredentials.UserName is populated whereas the ClientCredentials.Windows.ClientCredentials.UserName is empty.
But if the Domain is specified, Xrm.Client.CrmConnection.ClientCredentials.UserName becomes null and Xrm.Client.CrmConnection.ClientCredentials.Windows.ClientCredentials.UserName populated, which led to the service trying to authenticate user as a Windows AD user so of course it would fail when running app from outside Windows domain. And it explains why the same app works inside the domain even with Domain specified in the connection string.
For more detail, refer here for my original post asking for help in Dynamics CRM Forum

Creating a url in controller in asp.net mvc 4

I am trying to send activation mail to the currently registered user.In mail body,I need to send a link like http://example.com/account/activation?username=d&email=g.Now, for debugging on local machine, I manually write it as localhost:30995/account/activation?username=d&email=g. But, when my port number changes, I need to rewrite it.
I tried another question
on this website,but, compiler gives error like url.action doesnot exist.
Please give me fresh solution as I am confused with that solution.
Use a Url.Action overload that takes a protocol parameter to generate your URLs:
Url.Action("Activation", "Account", new { username = "d", email = "g" }, "http")
This generates an absolute URL rather than a relative one. The protocol can be either "http" or "https". So this will return http://localhost:XXXXX/account/activation?username=d&email=g on your local machine, and http://example.com/account/activation?username=d&email=g on production.
In short, this will stick whatever domain you're hosting your app on in front of your URL; you can then change your hostname/port number/domain name as many times as you want. Your links will always point to the host they originated from. That should solve the problem you're facing.
Try using IIS / IIS-Express instead of Casinni web server that comes with visual studio.
You could add bindings to have the right URL (with host entries of course).
This will avoid the port numbers in your links.

Note: If you are installing the application to a remote server you must modify the PortalAlias field value for the default record in the Portals table according to the rules defined above.
I look into the database dbo.portalalises but there is only 2 entries of portal but i have 3 portals..i think it can't generates the portal id automatically?
how this error be solved?
Check your permissions on your web folders match those of the AppPool your site runs under on the new host
Verify your database connection and permissions
Verify that your entry in the PortalAlias table in the database is correct for your new host
For anyone having this issue, I had the same issue, after I made sure that I have updated the "Portal Alias" table in db, to have a HTTP Alias (for my local host, I set it to localhost:8089 which was equal to what I had set up in IIS binding for DNN website), with the portal ID of 0 (as my portal id was 0), I was checking to be sure I have updated web.config file with data base connection strings, but then I realized there were two points for database connection in web.config, and I was missing one of them. So make sure to update both two connections as:
1) <connectionStrings>
2) <appSettings>
Hope this helps.

Note: If you are installing the application to a remote server you must modify the PortalAlias field value for the default record in the Portals table according to the rules defined above.
I think your are trying to host website in server where you don't have a domain called "Experiment".
Check the last line given in your question : "Note: If you are installing the application to a remote server you must modify the PortalAlias field value for the default record in the Portals table according to the rules defined above."
So check the values in PortalAlias table and specify the domain name (localhost may work).
