Error 90006 and lot's of delay.

[Yeshes]

Ever since I started FFXIV weeks ago I haven't had any technical problems, until the last 2 days where i reached the end of Stormblood and have had a massive delay/lag: npc's take more than 3 seconds to respond, trouble with activating skills and everything stops mid dungeon for more than 20 seconds and then I crash. It seems none of my company members or friends have been having the same issue but me.

My pc specs fit the requirements, I've tried re-opening the game as administrator and turned off my antivirus. My internet has not been a problem either.
Not enterily sure if it has to do with the game running on Steam or not...

Light Server: Twintania

my specs:
operating system: Windows 10 Pro
processor: Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz 3.19 GHz
memory: 16,0 GB
video: NVIDIA Geforce RTX 2070

Would love some help and/or advice on how to fix this, thank you!

Here's what my initial efforts reveal - in this article from 2017:

"Some Stormblood players have experienced frustrating problems in the form of error codes 90006 and 90002, usually ending up in disconnections from the Gaia data center.

Square Enix has announced the cause for both of these frustrating error messages. They're displayed when players log into the Gaia data center, as the official Square Enix blog states, and the company originally took "tentative measures" to address the issue.

As of June 17, Square Enix states it has monitored the situation and has found that these errors have been improving, slowly but surely, but the situation is still going to be monitored going forward."

Perhaps someone in the development or QA teams should revisit that item and see if whatever was causing it then has somehow been reintroduced?

I ask because this is precisely the behavior I'm seeing since roughly Monday and I have no way to try reproducing it as I cannot determine why it's happening.

edit to add:

Personally, it 'feels' like they're pegging load balancer caps. Perhaps due to new accounts? Or some kind of DDoS happening. More likely the former than the latter, honestly.
