Error connecting to database MySQL

my website is and it suddenly stopped working, giving me error connecting to the database. Now I cannot enter into the database, even from the administration panel: PhpMyAdmin gives me an error connecting to the MySql server (#2006 - MySQL server has gone away).
There are some issues on the database server?

Thank you

Sounds very much like rate limiting, once you’ve exceeded the free limits your database is frozen for a few hours sometimes.

Wait it out :100:
