Cannot login after PHP upgrade to 7.2

Nextcloud version: 16.0.3
Operating system and version: CentOS 7
Apache or nginx version: nginx 1.14.2 with php-fpm
PHP version: 7.2

The issue you are facing:
After upgrading PHP to 7.2, I cannot login anymore using the browser.
The desktop app is still working fine and able to sync files
CalDav on my Android phone is not complaining either
When I try to login I just get redirected to the login page again.
This originally happened with Nextcloud 15.0.10, but I’ve since upgraded to 16.0.3 without any effect.
One other thing I did earlier was enabling 4-byte support in MySQL, not sure if that could have anything to do with it.
I’ve tried

  • disabling the cache (I was using the APCu module before)
  • resetting the password

When I log in using a wrong password, I get exactly the same result, the page reloads and there are no error messages. I did not find anything useful in either of the

  • Nginx logs
  • php logs
  • Nextcloud logs

The output of your Nextcloud log in Admin > Logging:
I cannot access Admin > Logging, but here is the log file
Note that I’ve set the logging level to 0, before there was not any output. The following segment has two login attempts on the webpage

Looks like this is the same issue: Nextcloud 16.0.1 Login Loop on Install
The PHP upgrade changed the owner of /var/lib/php/session/ to root:apache, I changed it back to nginx by sudo chgrp -R nginx /var/lib/php/session, then restarted through sudo systemctl restart php-fpm, now login works again!
