Since 21st Friday I am unable to login to RPH, getting this https://imgur.com/a/QUJ2R
I also have the same problem (DC'ing/Unable to Connect) to Blizznet and Steel Division (Steam RTS). Interestingly, I am able to connect to other private-WoW server (2.4.3 TBC) without any issues.
To this date, I have tried:
-Updating my system and drivers
-Playing with my Firewall
-Renewed my IP
-Switched files with a friend of mine whos' client works
Do you have any tip? I should let you know that I can play other games as fine as ever (DotA, War Thunder and Insurgency is what I play the most).
