Hi,
I am trying to set up MySQL for my bungee cord servers but whenever I try to connect it it says:

========== UNABLE TO LOAD PERMISSIONS BACKEND =========
Your configuration must be fixed before PEX will enable
Details: Unable to connect to SQL database
=======================================================

I am using a host called Scalacube and they provide a MySQL service and I have manged to use it with other plugins but they set out the MySQL config differently
I have tried lots of different URLs but nothing will work.
Here is my config.yml:

multiserver:
use-netevents: true
permissions:
debug: false
allowOps: false
user-add-groups-last: false
log-players: false
createUserRecords: false
backend: sql
informplayers:
changes: false
basedir: plugins/PermissionsEx
backends:
file:
type: file
file: permissions.yml
sql:
uri: mysql://**********.scalacube.net/pex
user: root
password: *************
type: sql
updater: true
alwaysUpdate: false

Sorry, found out what the issue was. I needed to include the port in the uri!

I'm glad you were able to figure it out. :)
