Guild Wars 2

I just noticed that I have connection problem with:

Auth1.101.ArenaNetworks.com
64.25.38.171:6112 – connect failed
64.25.38.72:6112 – connect failed
64.25.38.51:6112 – connect failed
64.25.38.54:6112 – connect failed
64.25.38.172:6112 – connect failed

Section completed in 1.50 seconds

Auth2.101.ArenaNetworks.com

206.127.159.108:6112 – connect failed
206.127.159.77:6112 – connect failed
206.127.159.107:6112 – connect failed
206.127.159.109:6112 – connect failed
206.127.146.74:6112 – connect failed

is it about the port 6112 that I need to open?
Because I have

Diag.ArenaNetworks.com
206.127.158.31:6112 – connect succeeded
206.127.158.31:80 – connect succeeded
64.25.39.21:80 – connect succeeded
64.25.39.21:6112 – connect succeeded

which has 6112, and it worked fine. Maybe is because the server where I was connected were in maintenance? (I received the warn that it will be maintenence while I was testing port 80)

I am so super confused

Same thing as Stalzy said, trying the port 80 shortcut, client downloaded a patch, connected for 30 second longer with spikes of lag, but at the end still disconnected as error 7.

I find myself in the same situation, Played no problem, since yesterday always getting this error. Impossible to play.
