503 error every day

Hello…
I’m facing an issue where my website gets 503 and/or 500 error every day between 09:00 AM and 09:30 AM (Indian Standard Time) for about 10 minutes and then get back normal by itself…
Even after restarting the server, it does not get starts… It only starts by itself automatically within 10 minutes…

I’ve tried systemctl restart gunicorn.socket but it didn’t worked as it gave me an error like “Unit not found”.

Also tried to update the cyberpanel, but it didn’t worked either…
