Plauged by 900001 and 90002 errors

For about a month or so now, I’ve been randomly getting both the 90002 and 90001 errors on PC. It’s been SO aggravating when trying to queue for anything or while currently running something and getting the error in the middle of a dungeon….i’ve tried the fixes in the internet options that I’ve come across in posts I’ve found years ago in Reddit and recently here as well. Nothing seems to work. Why is this happening now? I wasn’t having a problem at all until like I said about a month ago and I just want to play without constantly erroring out. This is the only game I have issues with connection.

90001 & 90002*

Same.
Started to get a lot of 90001 errors the last couple weeks for seemingly no reason.
I didn't change anything in my system and it is not my Internet connection problem,
cause there are no disconnections or package losses to the server's IP address.

Everything was fine for the first couple weeks after DT launch and now it is barely playable.

No VPN.
Wireless.
Windows 11.
I play on 1 character.
Disconnects randomly at all times.
Multiple times per day can be 1-2 to like 5-10 times.
Service provider: Cox
North America, AZ.
Completed Windows updates, checked internet options, etc.

Also I should add, my fiancé plays as well in the same household but on Xbox X wirelessly. He never DC’s. I never had a DC problem when I played on PS5. Only when switched over to PC. It’s so frustrating. Might just switch back to PlayStation soon if it doesn’t chill…sucks when you can trust your connection enough to play a tank or healer class in any party instances because you’re afraid of DC’ing on everyone.

can’t trust*

It could be this issue that's still an on-going problem. https://forum.square-enix.com/ffxiv/...server-network

No idea…but it makes the game unplayable at times which sucks since we pay a sub and all.

This has been happening to me as well this past week or so. Infrequently. but often enough to be annoying.

Too may issues going on with the game since the launch of DawnTrail. I have investigated everything and none of it is on my end.

I've also been plagued with bad internet when playing FFXIV during raid nights. I've noticed the issue when progging thouhg m3s and noticed my ping get spiked to 300 ms, and disconnected 3-4 times during prog nights (monday, Tuesdays, and Fridays 8 PM - 11 PM), and this keep going on till 3:00 AM as well, when i am helping folks out too.

However I've not yet had 300 ms ping happened but instead I got 5 disconnections during progging on M4S yesturday at around 8 PM - 11 PM, and ping was jumping from 80 ms to 150 ms, and everything was sooo laggy, and sadly it seems to be only me. We usually moved to dynamis, mertlith server, and this been happening.

If I don't clear M4S at all, or get replaced from my raid team due to this shitty connection I have with the game during raid nights, i'm might as well unsub the game and won't come back till next expansion.

I've been having the same issue as well for the past few months after DawnTrail was released. Either that, or the game would crash without an error message at all.

Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums.

The issue you are describing is most associated with interference with game data. Many actions can trigger this error, such as a slow internet connection, certain security/privacy changes on the default Internet browser, an application running in the background causing interference, use of a VPN or an odd connection (EG: schools or cafes), a possible virus detected on the device, many rapid payments at once, and numerous other actions.

We advise clearing the cache/cookies/browsing data from your default web browser, disabling any web browser extensions (EG: ad-blocker) and trying again. We also suggest resetting the connection (router/modem) you are using to connect to the Internet before trying again.

Open the control panel of the PC and go to ‘Network and Internet’. Once there select ‘Internet Options’
- Under the "General" tab, please delete ALL browser history.
- Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
- Under the "Privacy" tab, click “Advanced” and select ‘Accept’ under both First Party and Third Party Cookies.
- Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
- Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED. [SSL 3.0 should be UNCHECKED]
- Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
- Right-Click on the FFXIV launcher icon and select "Properties"
- Hit "Apply", then "OK" to save the changes.
- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"
*Make sure your fire wall or antivirus program is not interfering with the game

Lastly, check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

Try disabling background applications and do a clean boot by opening the task manager and selecting the “Start up” tab. Disable everything and then restart the PC.
Lastly, we suggest to power cycle the console and router by shutting down the Router and leaving the power supply unplugged for 5-10 minutes.
