OK, before you say read this https://forum.nostalrius.org/viewtopic.php?f=45&t=12567 I DID read it, especially those 2 topics viewtopic.php?f=45&t=5359 and viewtopic.php?f=45&t=11569
From what I saw, my problem is when you have chosen wrong realm. But that is not the case for me. The first time I logged in, I logged into a correct realm (aka Nostalrius Begins).
This is what happened when I logged into 1st.
It told me to pick the realm whichever I wanted (there were a lot of realms, 3 of which were developer and 2 were player test I think, only one said Nostalrius Begins) and I picked Nostalrius Begins. Then I created my character and exited the game without entering the world. Why? To download recommended addons from this forum. I installed a lot addons so could this be the issue why I can't connect?
I have disabled firewall and checked my realm list more than one and still nothing. I even deleted WTF folder and nothing.
Is your server down? Was looking foward to play some nostalgic vanilla wow.
Sorry if i posted this if it was not needed and if the problem was known. I read a lot of those and it seems I am not the only one. But out of those, they say it was fixed for them.
