According to your description, I suggest you could try to enable the Failed Request Tracing to capture the hanging requests. You could use it to set rules that capture traces when requests to specific URLs exceed a time limit, or fail with specific errors,
To enable FRT rules, run:
This will tracing the request exceed the 30 seconds and generate the FRT XML. Then you could analysis the xml and find out the reason.
%windir%system32inetsrvappcmd configure trace "Default Web Site" /enable /path:test.aspx /timeTaken:00:00:30
