Is it PHP 7.4 or something else causing the errors?

I’m seeing the same in my nextcloud log.

Anyone have an idea of where to start looking?

My PHP and PHP-FPM logs are clean.

bump. Still getting these errors filling my nextcloud log.

anyone solve this yet?

The same error with me, but my web login does not work, phone app works.

Migrated from old server to new one, also new clean install does not work.
