Site offline with 500 Internal Server Error after update from 2024.12 to 2026.01.

Hi there,
after succesfully updating the site several several times lately, trying to get it to run friendica stable the last update just got stuck.
Calling the site gives 500 error message.
In a first attempt to trouble shoot the situation I did the follwoing.
I stopped the cron job by quoting out the respective crontab -e line.
Than I tried to set the site into maintanence mode by using the description as detailed in https://forum.friendi.ca/help/admin/migrate:

bin/console maintenance 1 "We are currently upgrading our system and will be back soon."

As result I got the following error message:

As update procedure I used the standard procedure:
git fetch
git checkout
Your branch is behind 'origin/stable' by 2025 commits, and can be fast-forwarded.
git pull
cd addon
git fetch
git checkout
Your branch is behind 'origin/stable' by 226 commits, and can be fast-forwarded.
git pull

Any idea what I can do to solve this?

show variables like 'max_connections'; shows 151 max_connections.

I did: SET GLOBAL max_connections = 200;

I also edited /etc/mysql/mariadb.conf.d/50-server.cnf and set max_connections = 200

Is this too high? Too low? Did I do this the correct way?

Thank you!

Thanks!
