503 errors while creating a new python web application

[tengteng]

I am new to this cpanel. When I am creating a new python web application. There are only 3 options of python version for me which are 2.7.18, 3.7.12 and 3.8.6,

If I am choosing the 3.7.12 and 3.8.6, the 503 error will be displayed but it works fine with 2.7.18 version. I cannot figure out this problem. Does anyone able to help me or give any documentation for me? I haven't put my source package inside this application but it already have this 503 bug.

If anyone met this problem before please guide me to solve this. Thank you!

Hey there! We aren't able to debug applications to that level on the cPanel side of things, but it sounds like the application just may not be supported in the more modern Python versions. It might be best for a Python developer to examine that application's code to see if there are any compatibility issues.
