Constant massive lag spikes, and occasional 90002 disconnects only FFXIV affected

[MrJibblets]

Hi all! I have been an on and off player since 2.0, and have had no real issues before. however recently (the last week) i have been getting constant brief lag spikes and occasional full disconnects. I am using the same router, modem, and computer that i have been using for the last year. I tried looking for some solutions such as using my vpn to put me in a different location, changing my IP address to googles, reinstalled the game, made sure all drivers for EVERYTHING were up to date, restarted my modem and router, and prayed to any god that will listen. any advice? (all other services work perfectly on my computer even during the disconnects with ffxiv)
