Unable to Connect - whats next step?

I'm getting "Unable to Connect ... [please contact Blizzard CS ...]" error message when I try to login. I do not get past connecting. I am playing on an unmodded version of the game that I downloaded from this website. I was playing a few hours ago before I DC'd, so it's not the gamefiles. I am logging in using my Warmane username and am in good standing.

What should I try next?

try this:
1) Restart your PC
2) close your Torrent client and move your WoW folder away from your Torrent's download destination
3) now right click on WoW folder> Properties> remove "read-only"

Done, Done, Done. Issue not resolved.

Hey, I'm having the same problem. None of the suggested fixes above worked for me either.

Anything going on with the server?

Same situation. This is treated with the usual expectation. This happens once a year on the server. We're waiting.

I also have this problem, I did this whole process and it didn't work.

Same here. Since the restart, when i try connect, say " unable to connect"

Same problem where too

Same problem here..

Resolved from OP. Unclear whether the server changed or it is because I swapped to a new internet source. I did nothing to my game files.
