When i start my Server this Error pops up:

[MLS] Error connecting to the database...
[MLS] Error: Can't connect to MySQL server on '185.101.92.238' (111)

Here is my MySQL_config.lua:

config.host = "185.101.92.238"
config.database = "mls_db"
config.port = 3306
config.username = "root"
config.password = "*"
