This issue is resolved now. I’ve not updated the gunicorn app name in my settings on Render. Instead of “web: gunicorn app:app” we’ve to use “web: gunicorn ‘Your_app_name’:app”. Which in my case was “web: gunicorn run:app”

Hi there,

Glad to hear you were able to resolve your issue and thanks for sharing the solution with the community.

Thanks for using Render!

I have the same issue and it didn’t help me

[divyanshbhatt527]

Oh! I’m so sorry. I made a mistake there. Instead of ‘Your_application_name’, it will be the name of your application file which is used to execute your application for the first time. In my case it was run.py

In my run.py file, I had the start command for executing for the first time.
