Im struggling with my setup lately. It worked just fine over the last period of time. After restarting my system the Nextcloud docker instance was not able to reach mariadb. At least I see an error when accessing the webpage. In the logs I was not able to find any abnormalities. When bashing into Nextcloud docker I couldn’t access data, which returns in an error not able to connect to mariadb. Which is weird because it was working fine before. I tried to overview the docker compose file which also doesn’t seem to show error. Then I checked the config file in Nextcloud where the Maria info is set. I’m kind of unsure what is causing the problem. Any help appreciated.
In case you need any more information like docker-compose and/or config output please let me know.
