Dungeon 900002 errors

Still waiting for some sort of solution as to how to proceed with this, as it is still happening and nothing I've done has helped so far.

Another 90002 Error Welcome to the club.
You may have contacted your ISP but have you tried an Ethernet connection if possible ? WiFi can be iffy at times and for all we know could be cutting out due to Chrome or even FFXIV needing more bandwidth than is steadily available.
If Ethernet doesn't fix the issue and you have done a trace from your PC to the SE server you play on, I would honestly contact SE support if a Moderator doesn't get back to you soon.

I get 90002 when I play the game with an unlocked FPS or lock it at 144 FPS, works fine if i cap it to 72fps but whats the point when I can get over 90 ? In the end I contacted SE support since it takes ages to get help here sometimes.
