Cannot connect to database-Error

[Player2]

Hello,

My website URL is: http://www.e-werk.epizy.com

What I’m seeing is:

An unexpected error occurred:
Cannot connect to database.

I’m using this software: ilch Version: 2.1.x

Since yesterday about 12 o´clock I cannot see my Page anymore.
I didnt change anything since then.
Any idea what´s wrong ?

Thanks & Greetings

Meanwhile it´s working again.
But I still don´t know why it wasn´t working for like 2 days…
