I have an application deployed to 2 Azure VM’s (Windows server 2022). These are load balanced by Azure load balancer.
Application proxy is set up to access the backend app securely. Connector software is installed on 2 VM’s.
The app runs as expected. However, if the app is left inactive for about 4-5 minutes, the error messgae “BadGateway: This corporate app can’t be accessed”. Details show that session is lost. The event viewer on the connector VM says, “Connection to the backend server failed. Error: (0x80072f00)”.
I’ve increased the timeout on the load balancer rule to max, i.e. 100. Also, ‘Enable TCP Reset’ is checked. Session persistence is set to ‘Client IP and protocol’.
- Is there any other place where I should check for timeout setting?
- Any resource I should be checking for mis-configuration?
- Is there a way to intercept the error page (badGateway) and provide a cutom user friendly page?
Let me know if any further info is required. Thanks.
