Can't connect to any databases after moving files to a new server

[hwittenborn]

I run a few things in Docker that connect to a mariadb database to function(Nextcloud, Standard Notes, all dockerized), and it all was working fine until I moved all my files to a new server, and now mariadb isn't accepting any connections.

Attempting to connect by running docker exec -it mariadb_container bash followed by mysql -u root -p and then my password results in the following error: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES).

This issue is only arising after transfering my files for docker(e.g. nextcloud container and nextcloud mariadb container) to a new computer and setting it all up again, after which no connections will succeed. I still have my files on the original server, on which everything connects just fine.

I don't do database backups(as in doing anything related to mysqldump), I just stop and run the docker containers. Again though, even with that, everything still works on the original server.

Anything I can look at? I'm trying to look around but can't find anything that's getting me any closer to solving this.

To move an instance from one server to another, the safest option is definitely going to be a proper backup/restore via something like mysqldump.

For more help, I'd suggest trying a dedicated support forum, such as the Docker Community Forums, the Docker Community Slack, or Stack Overflow.

I'll see if I can get that working then, otherwise I'll head over to those places.

That's all then, thanks for helping with what you can.
