I am evaluating Azure VM with MSDN subscription. I created a few server 2012 VMs. However, apparently Azure timeout the connections idle after a few minutes.
How to extend the timeout period at the Azure side?
This might be bit late , i update the response anyways . ITs possible to increate the time out by updating Keep Alive setting in the registry. This setting causes to send “heartbeat” packets to connected clients every so often. With this setting the connection can be prolonged.
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal
Services] "KeepAliveEnable"=dword:00000001
"KeepAliveInterval"=dword:00000001

So...about 5pm 2 nights ago, all 14 of my listeners on my Azure Service Bus dropped. So I logged in to my on-prem SQL Server to check on my Hybrid Connections and both of them showed a status of "Status Unknown". I can't find anything on the internet about this specific status.
Nothing changed on my SQL Server other than the fact that I've pegged the RAM....it's at 100% usage.
If I go to the Azure Portal, navigate to either of my Hybrid Connection Overview pages and click on the "Hybrid Connection Url", I get the following message in the browser:
"error": {
"code":"TokenMissingOrInvalid",
"message":"MissingToken: Relay security token is required. TrackingId:*SOME GUID*, SystemTracker:*SERVICE BUS NAME*:*HYBRID CONNECTION NAME*, Timestamp:2021-08-04T04:19:16"}
}
Now....I didn't change anything on my Hybrid Connection configurations. I haven't changed anything about tokens. I have no idea what's going on other than my Azure App Services have been down for 2 days, now.
Any help would be greatly appreciated....
This looks like an authentication error where a token might not be generating when you are trying to make a call to the underlying On prem server
You can refer the SO thread for ServiceBusAuthorization and still if you are facing the issue kindly raise a ticket with MS-Q&A
Microsoft support led me to this article where I found the following information:
Make Sure that the Date and Time are Correct
The Hybrid Connection Manager connects to Azure Relay using Secure Sockets Layer (SSL) on port 443. If there's a problem with your SSL handshake or connection, it will break your Hybrid Connection. If you find that your Hybrid Connection works initially, and then it stops working after about 10 minutes, that's a sign that you need to check the date and time on the machine running the Hybrid Connection Manager. Make sure they are correct because if they're not, your SSL connection may not work.
Well...the time on my server was off by about 16 minutes b/c of a group policy that I had never bothered to fix b/c I don't know anything about group policies. So I looked up how to fix the server's clock and, once that done, resolved this issue.
Could you please show me how to manipulate Azure connection idle timeout?
Now I am using Azure VM and host my web application in IIS. My App calls rest service from the outside network and it takes 5-10 minutes to get the response back. I have read that Azure will close any connection if there is no response more than 4 minutes. I tried to set idle timeout to 30 minutes from the Azure portal public IP configuration, but it doesn't fix the issue.
I have a little problem while using hybrid connections in Azure to connect a local resource. I installed the connection manager successfully and established a connection to the on premise resource, everything works fine...
But after around 20 minutes the connection gets lost until I restart the azure hybrid connection service on the on premise server.
The AppService is connected to more than one server and all other connections work well. Does anyone have an idea how to fix this problem and establish a stable connection?
We encountered similar issues with Azure endpoints. We resolved it by having a scheduled message sent to the local BizTalk web services every 3 minutes to keep it alive.
We are running some long-running test apps with Azure Service Bus relay over http, hosted in a windows service and most of the time, these run fine for 2-3 days. However every so often an internal network glich may occur (e.g. firewall reboots) that kills the internet connection.
At this point, the relay is dropped in Azure and our web app can no longer communicate with the on-premise service.
I would have thought that the Azure relay client was fault-tolerant - in that if it realises that it's lost connection with Azure then it will re-establish the connection andf if it can't keep trying until it can.. but it appears that this is not the case. This seems pretty fundamental...?
Only once have I ever seen a "System.ServiceModel.CommunicationException" where the service can't communicate on the internet, and that was when the client was starting up and trying to establish the connection in the first place.
Is there any advice or feedback on handling transient disconnections through the relay service (as it's a cloud --> on-prem direction then the client can't AFAIK ping the server).
If you are still experiencing issues, you may want to contact Azure support to understand why it is disconnecting. The Relay client should reconnect if something happens to the existing connection.
You may want to add ConnectionStatusBehavior to your ChannelFactory to have it output when the status for the connection changes. It will contain the error that caused it to change status.
var connectionStatusBehavior = new ConnectionStatusBehavior();
connectionStatusBehavior.Online += ConnectionStatusOnlineMethod;
connectionStatusBehavior.Offline += ConnectionStatusOfflineMethod;
channelFactory.Endpoint.Behaviors.Add(connectionStatusBehavior);
This issue is solved by Microsoft in version 2.6.5 of Microsoft Azure Service Bus dll. After 1 month of testing it seems to work.
I have an MVC 4 website using a WCF service. When I deploy to Windows Azure using the VS 2012 publish wizard, I get this error:
10:13:19 AM - The HTTP request to 'https://management.core.windows.net/42d4257b-5f38-400d-aac5-2e7acee9597d/services/hostedservices/myapp?embed-detail=true' has exceeded the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout.
After cleaning the project and publishing a few times, the error goes away. What am I doing wrong?
Whenever you start publish process from VS machine, a SSL tunnel is established first and once the tunnel is created, the package is transferred from your machine to Windows Azure Portal first. After the upload is completed, you will see the result notifications are posted back to Publish result windows and that is how it happens.
In your case, the time to build the SSL tunnel doe secure package transfer is longer then normal, this could be because of network latency between your machine and the Windows Azure Management Portal. For security reason the time to create the tunnel smaller windows and if the connection is not created, the retry cycle starts the process again and even if that fails you are greeted with the failure message. This could be caused by excessive traffic on either side or both sides. So this is mainly a networking related issue rather then specific to Windows Azure as after some time successive tries, you could upload your package.
In such failure/situation, you can run network capture utilities i.e netmon, wireshark, and see the time taken during failure and success to see the different in various transfer. This will help you to understand the underlying delaying issues.
