I haven't been active on the PvP scene in years, but there was a third party program that led to this if you weren't using the same program. It was an issue known both to dev and those using it some time ago, and my understanding was that use of said program, prevalent at the time, was on a major downslide for reasons best unstated. I really don't know what your issue is, and am not savvy enough to comment really, just beware, there may be absolutely nothing at all "wrong" with your machine or connection. For what its worth!
