There is one thing more as we have checked together his ET folder and everything is fine there ,maps server , server files etc..
Also I was online in jay3 and saw Maky connecting , I think he is not blocked by ISP I mean IP blocked
Now Ii think his PC is fine.
I know he is used netgrear router , and this kind of rout got blocked list and firewall system
that can doing or coz problems like this awating gamestate.....
I think its time to remove all blocked list IPs and tern off router firewall ,
Try this steps :-
1. Open Internet browser and access
http://192.168.0.1
2. Enter admin for username and password for password.
3. On the left panel under Security ( Content Filtering , for older devices) , click Firewall Rules.
Remove anything can block ET or game servers IP.
