Guild Wars 2

I’ve started getting that error this evening, I keep getting kicked back to the character select screen either whilst loading or playing. Have tried all my characters and it happens on each of them. I last played on Monday night with no problem at all. Have searched for Pando as suggested on the other post but I don’t seem to have it installed

Error code 42:0:9001:4105 on some attempts, 42:1020:9001:4103 on others
