Good Day Y´all!
Since yesterday my whole iRedMail Installation seems to be all over the place. I´ve done some maintenance on the installed software packages and did an update.
A few minutes later I noticed that the roundcube Webpage and IMAP logins from Mail Clients were not working anymore. The Site keeps loading forever and just spits out a timeout (same on the mail clients). My Nextcloud Installation, which happens to be on the same MariaDB doese´nt work either.

The /var/log/mysql/error.log contains some Intresting Information.

Re: MariaDB error after apt upgrade

So, i seem to have fixed the issue.
After reinstalling mariadb and restoring all databases, all seemed to work fine for a short period of time. After 3-4 min i couldnt get a connection through webmail nor imap. But this time the logs /var/log/mysql/error.log were seemingly fine. Later i discovered, that my home IP had been banned by fail2ban (besides ssh nothing was open anymore). I forgot to update a changed password on my phones Mail client. So it locked me out.

TL:DR
The original Problem was fixed through reinstalling mariadb. Still dont know what went wrong.

Cheers
