Done Error trying to join, pic below.

So, I've just tried to join the server for the first time in like a year or so and I keep getting an error (pic below). I've tried to join in 1.10.2 Forge and 1.8.9 Forge, neither work. All my other servers work, just this one doesn't. Any idea people? Thanks

 

What are you trying to join? There is 2 pixelmon on different versions.

 

Sorry, worked out what to do, decided to use launcher. Question about the launcher though:

It tells me to download and add Pixelmon 5.0.0 - Beta 7 via it and I've added it 3 times now yet it's not working. Do you know why this is? thanks [DOUBLEPOST=1474753684][/DOUBLEPOST]

This is what I mean



EDIT: Also proof that I have it downloaded

 

Restart your launcher. I mean like close down minecraft, and exit out of the launcher. Then re open the launcher and try again.

 

done 3 times...

 

what ip are you connecting to?
