Error 5 when trying to join Desert BL

Hi,

I'm a EU player on US servers (i don't know if that matters) and I'm currently experiencing a weird error 5 (5:11:3:159:101) when trying to join the Desert Borderland (no matter what the character). Everything else works fine, i can even join Alpine BLs, EB, Tyrian maps ... but as soon as I try to join DBL the game dcs. This connexion issue has been going on the last 24 hours since last patch (i was at that moment defending a tower in the DBL if that can help ...). I have restarted my router, my PC, launched the repair tool ... I'm out of ideas ^^

Oh, well, now I also have some random issues logging in the game (err 58:11:5:535). Some times i can, others i can't- checked firewall and all , everything's green on my side.On the bright side, now that WvW reset, i can again get on Desert BL ?!
