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

Can you elaborate on the kind of crash you are having? Do you receive any kind of error message? When you try and log back in, what exactly happens?

When did this start happening? Do you recall anything changing/updating on your PC or home network that coincides with this?

What have you tried so far in order to alleviate the issue?

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