Updated to solve nignx issue now have another

Hi guys hope your all well, not been around awhile.

Anyhow, after the last update i noticed i had the nginx issue so did a update and upgrade and got an email saying

Can’t connect to MySQL localhost
ERROR 2002 (HY000): Can’t connect to local server through socket ‘/run/mysqld/mysqld.sock’ (2)

My website seems to run ok so dont know what the issue is?

Thank you

you can ignore that, you probaly upgraded mysql aswell which lead to a short service downtime and this cron job email.
