Someone any idea, I’ve been struggling with this for some time.
I'm using SignalR (Asp.net 5). when I try to debug local (ISS 10.0 express) everything is working fine. SignalR is working (Long poll).
Now when I publish the app to Azure it I can access : .azurewebsites.net/signalr/hubs
but I cannot access .azurewebsites.net/signalr/hubs/negotiate
it returns:
The specified CGI application encountered an error and the server terminated the process.
When my web app calls $.connection.hub.start() it will fail.
GET XHR http://xxxx.azurewebsites.net/signalr/negotiate [HTTP/1.1 502 Bad Gateway]
I’m running out of idea's. Don't know how I can get more debug information.
Small selection of my ‘already tried’ list:
Set $.connection.hub.url path manual to http://xxxx.azurewebsites.net/signalr/
Enable/Disable websockets
Removed forwardWindowsAuthToken from the web.config httpPlatform
EDIT:
Now getting more details on this error:
CryptographicException: The data protection operation was unsuccessful. This may have been caused by not having the user profile loaded for the current thread's user context, which may be the case when the thread is impersonating.
Still absolutely no idea how to solve this!
Solved by using appBuilder.UseAesDataProtectorProvider();
(from Owin.Security.AesDataProtectorProvider;)
I have no idea if this is the best solution.

I have created a UWP application for testing purposes in which my purpose is to be able the application to connect to a ASP.NET Web API with a certificate for Indivual User Accounts, I've hosted the db into localhost, after ensuring the connection its correct and everything its ok I have deployed my UWP app, the problem is that when I execute a call to a method inside the Account controller (api/Account), the compiler throws me an exception which is the following:
System.Net.Http.HttpRequestException
Message=An error occurred while sending the request.
Source=System.Net.Http
...
Inner Exception 1:
COMException: The text associated with this error code could not be found.
The certificate authority is invalid or incorrect
I have searched for the problem but there's not a "specific" or "correct" answer I've found, could anyone help me with this issue please?
if code snippets are required, let me know!
I tried following links to generate server side SignalR trace on my production environment:
http://www.asp.net/signalr/overview/testing-and-debugging/enabling-signalr-tracing#server_text
https://github.com/SignalR/SignalR/wiki/Tracing-on-the-server-side
But, trace is not getting saved on disk as mentioned in the links(e.g., "default_traces.txt" or "transports.log.txt" respectively).
Please suggest where trace log file get saved?
I also checked following folders mentioned in first tutorial:
C:\inetpub\logs\LogFiles\W3SVC1
C:\inetpub\logs\FailedReqLogFiles\W3SVC1
But nothing related with SignalR found there. Any idea?
In my environment (VS2015 + IIS Express) log files are stored in web application folder (folder with web.config).
Be sure that your application pool has write permission on logs folder.
Also check SignalR error on client side. It can direct you to the cause of the problem.
For example, if client receives response 401 (Not authorized) (for example, on $.connection.hub.start()) it could mean that authentication middleware can not authenticate the client and responds with 401 without passing the request further through OWIN pipeline to SignalR. In this case SignalR does not emit any logs (it doesn't know about any request).
I have been trying to create a web api 2 that is secure with individual account.
So I can easily create WebApi2 with individual account, see link below
http://www.asp.net/vnext/overview/authentication/individual-accounts-in-aspnet-web-api
And Self hosting is easy to do.
http://www.asp.net/web-api/overview/hosting-aspnet-web-api/use-owin-to-self-host-web-api
But I cannot figure out how to combine the solutions.
Far as I got was adding a console app to a webapi2. Which seems to run. But whenever I try and get the access token it returns
An unhandled exception of type 'System.Net.WebException' occurred in System.dll
Additional information: The remote server returned an error: (500) Internal Server Error.
If anyone knows of a solution that would be great. Thanks
This post is way old, but to anyone else who is having this issue and finds this question, I was able to get past the 500 Error by adding app.UseWebApi(config); after setting up config, as mentioned in this post:
http://odetocode.com/blogs/scott/archive/2013/07/24/self-hosting-webapi-with-katana.aspx
HOWEVER, I'm now getting a 401, unauthorized request for all of my requests, even though I have a valid token and I'm sending it the same way I did that worked in the non-self-hosted WebApi2 app. but I'm one step closer anyways.
I am using reCaptch in my MVC 3 web app running in the localhost.
Things were working fine few weeks back but suddenly failing.
Suddenly getting this error.
if(!ReCaptcha.Validate(_config.RecaptchaPrivateKey)){ <-- times out here
//process other fields in the form
}
As soon as I fill the form and hot submit I get this error :
The operation has timed out
Description : An unhandled exception occurred during the execution of the current ...
Exception Details : System.Net.WebException: The operation has timed out
Is this a proxy issue?
Is this because my site on localhost runs on port 3316?
localhost:3316/user/signup
I saw some posts that suggests that reCAPTCHA expects port 80 but my app runs on port 3316
What can be the issue?
Thanks
I got around this by creating proxy class that inherits IWebProxy.
Then specifying to use this proxy when internal, I had to transform it out for other environments that didn't need to use it.
See this question and accepted answer:
Is it possible to specify proxy credentials in your web.config?
The above link took some finding, so I favourited it for future use.
On II7 we host a WCF/asp.net based API. In order to allow users of a classic asp application to connect to the API we had to publish a version we refer to as "transport". This Transport version is written in asp.net too, it points to the same assembly , its just the security layer is different to allow classic asp to authenticate. Transport level security is used as opposed to message based security.
When using a browser to load the service reference i can loading the svcutil.exe ... WDSL page.
When using my test asp page to call a web method from this reference i get the following returned:
Finished calling Web Service.
Status = Internal Server Error
ResponseText = a:InvalidSecurityAn error occurred when verifying security for the message.
This suggests that the authentication is failing. When testing using asp.net or the application WCF storm to contact the normal API everything works well.
The API was recently migrated , it would appear something has not been setup correctly but i am at a loss to explain what.
I can browse to the svcutil.exe ... WDSL service reference, when selecting it via the browser i get the expect XML response.
The USER NAME and password utilised work when using the non-classic asp publicaiton of the API using the message based secuirty.
Would it be possible to post some troubleshooting tip that may help diagnoise the issue please specifically regarding transport level security fault finding and setup ?
Thank you
Scott
EDITED TO ADD THE FOLLOWING UPDATE:
Attempted to use the Default App Pool and a new App Pool but same problem persists.
My test page error: ResponseText = a:InvalidSecurityAn error occurred when verifying security for the message.
IIS LOG shows:
v3/transport/testclassicasptransportwcfservice.asp ( 200 0 0 ) (i.e iis 200)
/V3/Transport/DeviceService.svc/DeviceService (500 0 0) (i.e iis error 500)
note: virtual dir defined on TRANSPORT and V3. V3 works ok using .net as opposed to classic asp to authenticate.
EVENT LOG:
The Template Persistent Cache initialization failed for Application Pool 'transport' because of the following error: Could not create a Disk Cache Sub-directory for the Application Pool. The data may have additional error codes.
This reference appears to suggest a fix but many of the DIR paths and references in "appcmd" dont exist.
_http://theether.net/kb/100127
REF http://theether.net/kb/100127
load cmd prompt
CD to C:\Windows\System32\inetsrv
enter: appcmd list config -section:system.webServer/asp
the following path is displayed: c:\inetpub\conf\temp\ASP compiled templates
check path exists (it does)
Check if the NETWORK SERVICE has permissions to access "ASP compiled templates" If not from appcmd execute;
icacls "c:\inetpub\conf\temp\ASP Compiled Templates" /grant "NETWORK SERVICE:(OI)(CI)(M)"
should read "sucessfully processed 1 files"
restarted app pool.
THE "InvalidSecurityAn error occurred when verifying security for the message" problem still persists but the "COULD NOT CREATE A DISK CACHE SUB-DIRECORY .... " error from the eventlog is no longer occurring.
Sorry another update. The network service permission change DID NOT resolve the issue , changeing to the DEFAULT APP POOL solved the problem.
Got a lead at last. Examined:
ServiceSecurityAudit set in service behaviour. Ref http://intrepiddeveloper.wordpress.com/2008/08/07/security-event-logging-auditing/#
IIS logs (simply shows the non-specific error 500.)
Fault tracing enabled( also shows error 500).
Custom errors were off
Friendly IE messages were off
Asp client side and server side debugging on
ProcessMon running , no errors.
Web.config httpErrors errorMode="Detailed" /> +
ServiceSecurityAudit found me an "Object reference not set to an instance of an object" so sounds like our app has a bug.
Follow up (17/08/11):
Service Security Audit documented here:
http://intrepiddeveloper.wordpress.com/2008/08/07/security-event-logging-auditing/
Was the key for us to resolve this issue. Uncovered the Object Reference Error which indicated out Business Objects and Data Access dlls were out of alignment. Using CLASSIC ASP to contact the WCF.NET API using TRANSPORT AUTHENTICATION there was abolutely no indication of this error until Service Security Audit was enavled on the behaviour.config file in the WCF deployment.
