I thought something like this happened a month or two ago as well and I never figured out how to fix it. Any idea if you’ll ever resolve this? Thank you!

Hi Teege – If you’re getting both error codes 26 and 42 it’s possible some ports may be blocked. Guild Wars 2 requires TCP ports 80, 443, 6112 and port 6600 be fully unrestricted and accessible, both inbound and outbound. If you are connecting to Guild Wars 2 while on a campus, military, or business network, please check with your network’s administrator to verify that these ports are fully opened and unrestricted.
