Guild Wars 2

Have been getting this code and getting kicked from the game since the last maintenance which is a real pain, as well as bad lag spikes (have been running smoothly before this)

Also got an error 42:0:9001:3928 (might have more but I didn’t take note of all of them)

What I’ve done so far:
Did a Diagnostic
Did a Port Test
Opened ports 80, 443, 6112, 6600

Hope I can get some help with this, thanks in advance.
