Downloaded the client and cannot log in

I've searched around a little and can't seem to find a fix. I thought it might just be easiest to ask here if any of you guys had the same issue at some point!
When trying to log in, with the info I used on the warmane website, I'm greeted with a " Unable to connect please try again later" followed by a link to blizz support. Does any one have any suggestions for me? I checked the server settings in the WTF and turned the " read only " off in properties already.

Same issue here, have you found any solution?
