Internal server error on one site (other site is correct)

Hi, I got an Internal server error on one site (other site is correct), I don’t see error in logs file and I have always an lock file in problematic site, if I delete the lock file erpnext recreate it after a reboot

I’ve tried bench setup nginx (Nginx config is correct)

thanks to help me

AFAIK, Internal server error comes when you have mentioned wrong site name or spelling mistake while setting site name.

You can run bellow command to start site.

Set port

bench set-nginx-port site2name 8080

Re generate nginx config

bench setup nginx

Reload nginx

sudo service nginx reload

My nginx is correct, was working before. My 2 site is on 80 but different domain name
