Not allowed to connect to this MariaDB server

If memcached is enabled, it will occasionally write this error to the error_log file.

Where can the error be or what?

The hosting provider told me to try rewriting localhost to 127.0.0.1. I did this in the config file, but the same error.

You need to keep the discussion with your hosting, maybe they missed something

or create a ticket

Thanks. I wrote to the hosting provider to see for them what could be wrong.
