PoE2 - Network spikes

Network lag keep shooting up, sometimes more sometimes less.
Connection is fine in every other game/app/browser, issue is in poe2.
The game became basically unplayable yesterday and it seems to be getting worse every day.
I also see a lot of similar posts being ignored, with many people complaining about the exact same issue, so this is clearly affecting numerous players.
Im waiting for a response from the developers and Im ready to provide any information needed to help find and fix the problem faster.

P.S. Please do not give me pointless advice like restarting my router, turning my PC off and on, or trying a different internet connection. I wasnt born yesterday - the problem has already been clearly identified and described.

having the same issue with 900mb optical fiber, its awfull i cant even do a single map
