Guild Wars 2

I’ve been unable to log in since recently reinstalling the game. The code error error 42:0:9001:4409 and says it’s related to security software or firewall. Sreencap of error is attached.

I have disabled the firewall and software (Kaspersky)
I have reset the router
I have set Port Forwarding as per instructions
I uninstalled and reinstalled the game.

Nothing is working and getting very frustrated. Really want to get back into game. Any help welcome

Same thing happened to me and my guild mates. Everything else is okay (browsing, youtube/twitch, downloading). Strange thing is, we’re from same ISP, everyone else is doing okay in my guild. After using -diag command, the log show 80-100% packet lost on anet domain (not sure if that is my ISP fault or Anet’s host).

Been getting a lot of those along with BLTC not working. I’ve tried disabling my firewall, forwarding all ports and the /clientport 80 thing. None of it has resolved this issue. If anyone has a fix, please let me know.
Edit: Practice mode works lag free, but I can’t whisper anyone or accept party invites, or queue ranked/unranked. Neither does my friends list show anyone online. I’m on a Mac.

@Knifesedge. I had the same problem, and also I have done everything i could… I wrote to Technical Support, and then they told me to uninstall " Relevant Knowledge" program. I have got win 8.1.
Check if it helps.

Yay i had same error and coudnt log too. I unistaled relevant knowledge and works for me. Ty Jakub for that hint.

THANK YOU SO SO MUCH! “Relevant Knowledge” did it. Read its a spyware. DEFINITELY delete it!
