Your very welcome

I see, my guess is that the path is in an nginx file somewhere. Could be the fpm config, but unlikely.

Nextcloud will look in the root of the nextcloud install for config/config.php

So unless you have been hacking the code, I think it’s nginx config

I can see the error log file, that has a very odd path in it. How are you running php?

Apache module or fpm?

Can you give a screenshot of the error?

Did you update the nginx config to point to the new location?

Does the user that runs nginx/PHP have write permissions to the new location?
