Please fix the random "90002" disconnect problem once and for all

Ever since Patch 5.5, Final Fantasy XIV randomly disconnect me from the game and gives me the following error message

"90002. Connection to the server was lost."

this has been a daily problem ever since Patch 5.5. It was never a problem prior to patch 5.5. In fact, I would never get a 90002 disconnect error before Patch 5.5 unless it was an internet outage or something. Now it happens every day, sometimes two to three times in one day.

I KNOW that it is NOT my internet as it often happens when I am in queue for duty and I am watching YouTube videos on my other monitor when the game disconnects with 90002 error. Nothing happens to the YouTube video, Spotify, or any other thing on my PC that requires a constant connection. Those keep playing. It is only the game that disconnects.Also, I am able to IMMEDIATELY log back in so it definitely is NOT my internet.

I was hoping that Patch 5.55 would fix the problem but it did not. Neither did any of the subsequent patches.

It just happened again before I started typing this post. One of my characters was in queue for Steps of Faith when we had 7/8 of a party minus a healer according to "forming party" and BAM! 90002 error, I log back in and it has been ONLY me in line for the last 20 minutes. I MISSED the duty with the six others because of a glitch in the game that was implemented in Patch 5.5


Please FIX this once and for all.

I had this issue myself starting pretty much with the beginning of Shadowbringers. My issue is my ISP hits a certain node when playing FFXIV and I would just disconnect every couple of minutes or maybe an hour later. I never actually "fixed" it as such, rather I always use a VPN now. I can't really play any game without a VPN but I'll sure take doing that than disconnecting many times. Hopefully one day it'll get resolved. :(
