Hi, first time posting and I need help

Hi, I've been playing on this server with a couple of friends for a pretty long time now, we had eventually stopped playing as much and recently I thought why not start up again. But whenever I attempt to join the server I'm met with an Error Message that states "internal exception: io.netty.handler.codec.decoderexception: i: non [a=-z0-9/._-] character in path of location: pslkeepalive" If anyone on the site or even Yom himself has any idea of what this is please help, I've been looking for a solution for about 3 hours now and the only answer I've seen is there's a problem with the server. It is ONLY this server, I've joined a separate public server several times and it was perfectly fine.

~Thank you for your time,

What version are you playing on? Try joining on 1.12 if you haven’t already

 

That worked perfectly thanks my man

 

Glad I could help
