Error connecting to database MySQL

[boncri]

Hello,
my website is nonnamaria24-bs.000webhostapp.com 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.

Rate Limiting Policy

As this is free hosting, there are going to be limits. However, what is available on the 000webhost free hosting platform is often abused by spammers. Because of this, we have implemented a new policy that limits the number of concurrent MySQL connections. These new limits are as listed below. 30 concurrent connections (per database) max_queries_per_hour = 15000 (DB read) max_updates_per_hour = 5000 (DB write) These limitations are already at a premium level and are subject to change…

Wait it out
