Tailscale, Mariadb, Synology NAS and mysql clients they don't like each other. Help

Well I have a MariaDB database set up on a recently purchased D923+. I’ve set up Tailscale and it’s working fine except when trying to connect to my database using various client software (MySQL Workbench and an iOS app called MySQL Mobile Client). I just keep getting the error: “Access denied for user ‘username’@‘localhost’ (using password: YES)”

Can’t figure this thing out for anything. I believe I have my users setup correctly. Tailscale is working as I can get to the NAS remotely with no problems. Just can’t get this connection to the database working. FYI I don’t have SSL/TSL running. Don’t know if that would make a difference.

I scoured the internet and found nothing.

Any help would be appreciated. Thanks.

I see this is a tough one, even for the pros. lol. If I get this working I’ll post here what the solution is.

Solved the problem. Had nothing to do with the above mentioned. Was totally user error on my part. Matter of user tables and databases. Everything working like a charm.

Thank you for reporting back.
