I've been getting random 90002 errors repeatedly while playing. The argument of checking your network router is not valid, due to the fact that I have 2 other people in the house playing FF14 with me. I'm the only individual receiving this error randomly, with no lag warnings. Just a sudden disconnection.

I've flushed DNS.
Set port forwarding for myself.
Application forwarding and unblocked from Antivirus.

Is there anything that can be done to stop these issues?
