Can't connect to server

Hi guys,

First post, enjoying this these last 4 days.

Yesterday I re-installed wow from blizzard app to see what's different after a 10 year break. Which immediately made me appreciate playing here.

I tried to load up my warmane wow and I can no longer login, can't get passed the "connecting" phase then a message saying to contact blizzard.

The only thing inbetween this is re-installing wow from the blizzard app so I'm assuming this has done something on the back end.

Can someone please guide me on getting Warmane back up and running.
thanks.
