I recently setup Kerio Control as Non-Transparent Proxy to access internet through it.
Sometimes I face an error Secure Connection Failed when I try to access any web page on the internet.
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Could you please help in this issue. Thanks!

I have an application running in a k8s cluster in AzureChinaCloud behind an ingress (internal load balancer) which in turn sits behind an application gateway with a public ip. The DNS point the URL to the public ip and all nslookups are giving back the correct address. The endpoint is HTTPS and the certificate is good and in date and correctly configured on the listener of the application gateway.
However 9 times out of 10 when I try the URL I am getting the below error
"Secure Connection Failed
An error occurred during a connection to blablabla SSL received a record that exceeded the maximum permissible length.
Error code: SSL_ERROR_RX_RECORD_TOO_LONG
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified."
However intermittently it does load okay. I cant match the failure timestamps with any failed requests in the app gateway logs. I ran a wireshark and I am seeing some errors like
[TCP Out-of-Order]
I see some RST messages from the client to the server
I also see some HTTP/1.1 403 Forbidden messages but I see some of these during the successful attempts also
If you create a website in china cloud you apparently need to register it with ICP. Below are the details I got from Azure support
Problem Reason:
There seems to be an issue with ICP registration.
More details about ICP registration:
According to the ICP filling requirements of China's Ministry of Industry and Information
Technology (MIIT) and China Public Security Ministry, a website is accessible only if the registration is completed and the filled information is accurate.
In addition, the access should be suspended if any prohibited content is published or disseminated.
If the website has not bound a custom domain, please bind your own custom domain with ICP filing for your websit
I need to connect to a third party webservice. When I hit the link directly in the chrome browser, I am able to connect to it and I get a response. But when I tried the same using Advanced REST Client app of chrome, I get a message as 'The service's server DNS address could not be found.'
Also, when I tried to connect it via my JAVA code, using spring's rest template, am getting an Unknown host exception. What could be the reason that am able to connect via browser but not otherwise?
Thanks in advance.
Maybe it's a problem with your system's DNS settings? I'm not sure how Chrome handles queries to DNS when primary DNS did not found the record. If it uses Google DNS' then Chrome may connect to the service but other applications can't.
To test it set your DNS to 8.8.8.8 and check if apps start working.
From browser it's working properly but not from rest client or application, then i guess the problem with the proxy.
if you are using your office network, then this issue will come.
Try hitting the webservice by connecting to personal network.
i have faced similar issue last week, from browser and postman i'm able to hit the web service but not from the application.
Ones i connected with my personal then it started working.
Hope it helps.
I need to set up Wi-Fi, where user after connecting to Wi-Fi will have to login to connect to the internet.
Like after he connects to Wi-Fi, he opens page in web browser. He will be automatically redirected to login page, where he must enter credentials and then he will get internet access.
I think that the router will somehow redirect the traffic over server in LAN and then some kind of SW running on the server will do this, but what SW should I use? I don't know how this is called, so I couldn't googled anything.
Thanks
So I managed to find it, it's called Captive portal, here is a tutorial how to do it: http://blog.trifork.com/2013/01/15/building-a-captive-portal-controlling-access-to-the-internet-from-your-network/
We are getting following error in Microsoft EDGE in our Dev environment when we run our ASP.NET Application Hosted in IIS 8 in Windows 2012 R2 Server.
Error:
XMLHttpRequest: Network Error 0x800c0019, Security certificate required to access this resource is invalid.
Following are more details about implementations and environments.
Our application runs on 2 different secured ports (HTTPS). In IIS both apps are hosting as different Web Applications and using same certificate. The certificate is generated using OpenSSL SHA2 encryption and it has been added in Secured Certificate Store.
From `Microsoft EDGE when we first load our application, it issues certificate warning message, and we are allowing to proceed. Once page is loaded, on a button click we are calling an API using AJAX call and that is hosted on different port.
In EDGE it is not allowing to proceed that API and giving above mentioned error.
In Chrome and IE 11 also, we are getting same warning message but from there it is allowing to execute next API.
Any help would be appreciated to fix the issue.
If you know your certificate is valid, a possible reason this might happen is if you have a tool running in the background somewhere that hijacks the SSL connections through a proxy, such as Fiddler.
Since such a tool is effectively using a man-in-the-middle attack to report the requests, the warnings are "normal". It's pretty easy to forget them running, too.

SSAS is running on a hosted server. No domain.
Able to connect with anonymous authentication, but when basic is enabled, neither SSMS or Excel will connect.
Error from SSMS is "The remote server returned an error (401). Unauthorized"
Credentials are set up on the remote machine as DOMAIN:443
Credentials have admin privileges on the server.
Excel says "connection cannot be made to remote machine or SSAS is not running"
HTTP or HTTPS doesn't matter.
When it connects with anonymous, no cubes are returned so it is apparently doing nothing with the userid/password. Just connecting.
When I connect via port 2383 using the same credentials, I have no problem in SSMS or Excel.
Help is GREATLY appreciated. Thanks.
This was partially solved by starting over and following the steps in this article:

Honestly, I can't pin down the exact resolution, but I believe it has to do with using a different folder structure (other than inetpub/wwwroot...) on my D drive and therefore losing the standard security configuration.
I created an OLAP folder on C:/inetpub/wwwroot and it works... with the exception of SSL which still does not work.
HTTP connects fine, but not HTTPS. Still working on that.
