I had this problem too! After running a few of the occ commands to confirm that maintenance was't enabled and everything looked fine (which it did!) I managed to track it down in the console. This error in /var/log/apache/nc-error.log: [Tue Mar 15 14:07:09.956155 2022] [proxy_fcgi:error] [pid 113:tid 22557371913984] [client 0.0.0.0:41080] AH01079: failed to make connection to backend: httpd-UDS [Tue Mar 15 14:10:29.766354 2022] [proxy:error] [pid 113:tid 22557420431104] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /run/php/php7.3-fpm.sock (*) failed This was because php has been updated from 7.3 to 7.4, I guess. I updated the apache config to replace the reference from 7.3 to 7.4 /etc/apache like so: conf-available/php7.3-fpm.conf: SetHandler "proxy:unix:/run/php/php7.4-fpm.sock|fcgi://localhost" Restarted the docker and now it works. I hope this helps someone
