Custom event details: 

Also error appears in browser as 500 Server internal error

Please we need help to figure out the cause of the issue or where to look

Answer 1

You appear to have the site configured to have a 30 second request timeout. Either bump up configuration, or better yet make your site faster. 30 seconds is pretty slow,

Answer 2

@Ali

You can try to increase timeout in iis to solve this problem.

In IIS Manager, right click on the website and go to Manage Web Site -> Advanced Settings. Under Connection Limits option, you should see Connection Time-out.

if not working yet, try using failed request tracing to see details about 500 error, this will generate detail log file, which will help you to identify the problem.
