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

Does this error come up immediately as you log into that character or after you have started playing?

These other servers that you've logged into successfully, are they from different data centers or are all of them on Chaos?

Can you list everything you've tried so far to alleviate the issue?

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