I can't access a minecraft server

I am trying to access a minecraft server named omegarealm but when i try i get this message Jsonreader.setlenient(true) Then it says something about line 1 column 2.

I'm confused on this matter, please help

Another note: for the version it affects versions 1.8 - 1.10
it wouldn't let me put those versions so i had to add a note.
