unable to join velocity server

I've been at this for some days now...

​

Not sure if I have multiple issues, or one large one. Currently I am trying to make a server for my friends that has a hub and multiple worlds for different modpacks. So far I am using Velocity as the proxy and Paper as the hub world. For the first modpack, I am using SpongeForge and or Arclight.

I have the hub server on port 25500, pixelmon on 25501, etc.

When using SpongeForge I am able to join the hub world, and type /server pixelmon and I get an error for "`unexpected custom data from client`". In the console, I get "`com.mojang.authlib.GameProfile@1233b1b3[id=2bab924b-b5b0-3b8f-9f49-d1ff2837aacd,name=thebebee,properties={},legacy=false] (/myip) lost connection: Unexpected custom data from client`"

When I try using Arclight I get the error "`Unable to connect to pixelmon: Your server did not send a forwarding request to the proxy. Make sure the server is configured for velocity forwarding.`" and in the console, it says "`thebebee (/myip): disconnected while connecting to pixelmon: velocity.error.modern-forwarding-failed`". However if I direct connect to localhost:25501 I am able to join the server, it is in offline mode so no one else can join and I don't have a skin, etc. So that leads me to believe it isn't a forwarding issue.
