Can't Login With a Specific Character

[Xamarel]

Hi there!

My husband is unable to login to his main, Lance Nesilvari of Lamia, both he and I have tried on our separate computers to login to that character, but we are getting a 90002 error. He last logged off after doing Weeping City a few days ago, and Returned to Idyllshire to log off. I created another character on his account, and am able to login to that character just fine, it is located on Malboro. My character on my personal account, Xamarel Nesilvari, is capable of logging in just fine, as well as other freshly made characters on other servers.

If it helps at all, we both use a wireless connection to our ISP-provided modem/router, on the 5ghz band. Our roommate plays FFXIV via PS4 on the 2.4ghz wireless line.

Any assistance is welcome, I would really hate to have to unsub because we can't play together at all.

PLEASE HELP. ;-;

EDIT: Hubby's character is now able to login. Didn't try much other than running around Idyllshire, but that's better than nothing, right? :P
