Hi, I've been having 90002 errors during the Level 80 Paladin Quest "Worth Fighting For." Although this is not the only occurrence of me getting slapped with a 90k; sometimes I will instead get a 90001 error in the mix, though I'm not sure what causes it, and I've been searching for all sorts of solutions or reading up on similar issues to find out what would be the most appropriate course of action I should take.

Some important things to note:

1. My internet stays connected even with the 90002 errors.
- Occasionally, there are 90001 errors and even more rarely, lobby connection errors.
2. I recently changed my ISP to Spectrum. Not really my choice but a family member has been complaining about download speeds - I was able to play FFXIV just fine before this change, so if it's an ISP issue, what is it I should call them about?
- I tried port forwarding too. Spectrum's app is awful because it won't let me input ranges (and what even is an External/Internal port? What does this even MEAN) and I don't know if I did it right, but there was an attempt, and I don't think this attempt worked.
3. The errors absolutely happen during the level 80 Paladin quest, but they've happened before, albeit randomly, during my run through the Shadowbringers Tank and Physical DPS questline, and the quest line after doing all role quests, and while I'm crafting, and while I'm interacting with my retainer, and while I'm queued. Basically, extremely randomly. I'm dying, Adamantoise.

This has been going on for less than a week, but I'm hoping to find out what it is I need to do.
