Yep, I'm having it too.

I tried the usual "troubleshooting tips" that seem to get posted by Moderators on problems like this:

Please try the following troubleshooting steps:

- The game will use the Internet Explorer web browser to connect to the internet. Open Internet Explorer, then open the "Tools" setting, go to "Internet Options" and adjust the following settings:
- Under the "General" tab, please delete ALL browser history.
- Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
- Under the "Privacy" tab, click “Advanced” and select ‘Accept’ under both First Party and Third Party Cookies.
- Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
- Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED. [SSL 3.0 should be UNCHECKED]
- Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"

-Make sure your fire wall or antivirus program is not interfering with the game

- Check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

-Try disabling background applications and do a clean boot by opening the task manager and selecting the “Start up” tab. Disable everything and then restart the PC.

All done. No change. Still getting disconnected with 90002.

The issue is getting worse as well. Last week I had this roughly every hour or so. Since this week l now I get disconnected twice in a dungeon run including queue of ~10 min.
So I‘m down to being disconnected at roughly every 20 to 30 minutes now.

Not enjoyable having to apologise to people for disconnects all the time.

EDIT:

I started an experiment today.
If it is not an actual connection issue of my PC (which I doubt it is) but rather routing issue (ISP) or connection issue on a FFXIV server/gateway (whatever) I might be able to get a stable connection when I change the routing or get connected to a different FFXIV server/gateway (whatever).
For that reason I installed a gaming related VPN. That way I should get different routing via the VPN and I assume since for FFXIV my location changed seemingly that I will be connected to a different FFXIV server/gateway (whatever).
I choose ExitLag: https://www.exitlag.com/en/
Because it has a 3 day free trial without credit card requirement however I would assume any VPN to work since from my point of view the all do the same… so Surfshark, NordVPN etc. probably work as well.

Anyway thus far no disconnect, no 90002 since my initial post. So yea this seems to indicate that the issue is most certainly not my PC or home network but rather either something with an ISP or the servers/gateways of FFXIV.
Of course this does not resolve the issue but rather bypasses it. However if you are affected give it a try since the trial time is free.
If it works for you maybe it is worth to subscribe such a VPN until SE sort this issue out.
