I'm running MySQL 5.6.30 - MySQL Community Server (GPL) on ubuntu-16.04-x86_64 and I'm using phpMyAdmin 4.7.7.

Sometimes, without doing anything on the Server or phpMyAdmin, I'm getting this error message on my websites:

Connection failed: SQLSTATE[HY000] [2002] Connection refused

When trying to log in into phpMyAdmin I'm getting these four error messages:

#2002 - No such file or directory – The server is not responding (or the local server's socket is not correctly configured).


mysqli_real_connect(): (HY000/2002): No such file or directory


Connection for controluser as defined in your configuration failed.


mysqli_real_connect(): (HY000/2002): No such file or directory

After making a reboot everything is working fine as normal, there are no error messages any more and I'm able to login into phpMyAdmin.

Why does it happen? Any ideas?
