I have the above issue today. I havent any issues since today with my mobile internet(last try yesterday night). I havent install anything, i tried port 80 solution ,no windows firewall or defender(only microsoft essential AV since the begin),tried the winsock reset and run as admin…..I also did restart both my laptop + mobile phone.
Here is the attached txt from game advisor.
Hi Saika – Mobile connections aren’t really recommended for playing Guild Wars 2 as they can be unstable. While there’s nothing wrong with using them, you may encounter issues such as this.
