the error is different when mysql is down. In this case i get: Error creating db connection: dial tcp [:1]3306: connect: connection refused

I've access the DB manually and it seems to work fine

fleet seems to work fine too, the webui is accessible and i can query my devices, it's just it fails when run fleet prepare db

i've rolled back the binary to fleet 2.2.0 and i get the same error, so it may be not related to the new version. The strange is that it worked fine last time i run it (when I updated the binary to 2.2.0)

ok, solved by specifying mysql_address, mysql_database, mysql_username and mysql_password parameters in the command line
