Guild Wars 2

Hello
I have a problem to connect to the game due to error code 5:11:3:159:101 I played it earlier today and this problem wasn’t there and since then no upload or patch were needed. I saw posts about this error but I really don’t understand computers so well and I would need some guide or something how could i get rid of this error so i could play i have only one character and i read also that there could be problem of having it back so i would need help with it too so i didn’t lost my progress.
Thank you

Here’s the explanation for that particular code:

Network issue. Failing to get connected to Guild Wars 2 may be caused by the routeur or by a network server failure. If the problem remains, please contact the online assistance.
