When i try to login with the launcher 4 out of 5 times it gets stuck on "succesfull", or i get disconnected.
When i succeed to login and i queue for a dungeon most of the time it takes like 2-3 minutes to load the instance and i am kicked out of the group and have to wait 30 minutes to requeue.
I have 2 different internet connections, 3 different computers and they all have the same issue.
I am a network specialist in real life, i have checked routing and packets with wireshark and nothing gets blocked or denied on my router.
I have a clean computer, no firewall, no antivirus etc etc...

I deleted WTF, cleared cache, no addons, ran the repair tool. but no results.

I am running out of options....

Now what can i do to have it fixed ?
