Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

Both of these error (the error message and the black screen) suggest that you are having trouble reaching the server properly. Aside from moving to a new location, what else has changed? Are you using a new ISP or router? Is the computer the same?

Did you make any other changes to your network? Are you using a wired or wireless connection?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
