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

Can you provide the full error message you receive?

This only happens with Shadowbringers-related content, correct? You don't run into any other issues while playing the game? Does this happen on any other characters (if you happen to have any other characters at that level)?

Can you submit a Final Fantasy XIV system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

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