Description

I'm running a velocity network. One of the server will be used for Pixelmon. After trying to set-up Luckperms multiple times, I can't connect to the server.

Console Messages:

1. User a03f31a1-536b-4235-9613-0d1bac11fc0c - Optional[Its_Lazzy] doesn't have data pre-loaded, they have never been processed during pre-login in this session. - denying login.
2. lost connection: [LP] Permissions data for your user was not loaded during the pre-login stage - unable to continue. Please try again later. If you are a server admin, please check the console for any errors.

Reproduction Steps

Installed Luckperms bukkit on the hub server & luckperms spongeforge on the pixelmon server;
Restarted both servers;
Changing the database settings in luckperms to where both servers connect to the same database;
Changing server name to Hub & Pixelmon;
Restart both servers;
After joining the hub, /server pixelmon, and I get the message mentioned above.

I've been doing research online and changed everything I could find on https://luckperms.net/wiki/Network-Installation

After that, I asked for support in the Discord. Recieved some responses from someone with the "helpfull" rank, but with no success.

Expected Behaviour

When being connected to the proxy it should allow me to join the Pixelmon server, it works without Luckperms, so as far as I know it can't be a proxy set-up issue. While both server link to the same database, I Imagine that after logging in on the first server it should pre-load my uuid for the join action on the pixelmon server.

The only other Sponge-Forge plugins that are currently installed are the following:
CommandPack-1.4.4-8.1.0-RELEASE.jar
LocaleAPI-2.6.0-S8.0.0-RELEASE.jar
regionguard-1.10.1-S8.0.0-RELEASE.jar
spark-1.8.6-sponge8.jar

And I'm pretty sure these don't touch the UUID either.

Extra Details

Server is hosted on a Dedicated server using Ubuntu & Pterodactyl. Made my own MySQL Database named Proxy and gave both servers access to it. (As for the database name setting, I've tried setting it up to where both servers had the same name, and another time to where both servers had the name set to the one specified on their respective database page.
