Reciving data screen only on one server

[idokoll 0]

I've been playing on a specific dayz epoch server for about a month with 5 friends, and from some reason me and another 1 of them can't connect to the server in for the past few days because we reach the reciving data screen. we've tried the obvious stuff but I really want to fix it so suggest what you got, also I was able to enter right after a restart to the server but once i logged of i couldn't get back in, plz help :((((
