After upgrade Ubuntu 20.04 to 22.04, nginx will not start

[vansens]

I followed the upgrade guide
After a reboot, I get this:

Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xeu nginx.service" for details.

Systemctl shows this:

Is there a backup of this conf file somewhere or can it be recreated?
Thank you!

Can you try to run /home/yellowtent/box/setup/start.sh via SSH and root on your server? This should rebuild the symlink of the config file to /home/yellowtent/platformdata/nginx/nginx.conf

Thanks, that worked!
