Keep Geeting 90k Error and Unable to connect to server Error for the past week.

[Shinjisake]

So for the past week I've been disconnecting in and out of game my friends in my free company have been having the same issue its for the Excalibur Server and its only happening to my friends that live on the East coast of America. I'm not sure what the issue is but the game is nearly unplayable at this point until very late at night. I'm guessing due to the fact of players logging off and going to bed during the day the game is nearly unplayable due to the constant disconnects i counted a total of 10 disconnects for myself alone my friend had 5 and another had 6 they stopped playing till late and night and we didn't disconnect again afterwords. I have even contacted my internet provider to see if the issue was on their side and they told me no the signal from them to my router is very strong but the signal connecting to the FFXIV servers is quite weak. Please help

-Platform: Pc Windows 10
- Error Codes: 900002
-Connection: Wireless
-Other programs: Google Chrome, Discord
-Frequency: 5-10 times a day dependent on how long i play
-Attempts to Resolve: Contacted ISP, Reset Router, Mainlined Connection, IP Renewal, IP Config, Firewall Config, Security Config (etc...)

Ive tried every trick in the book to get this issue resolved and nothing has worked. It Always happens throughout the day as if the Excalibur server has to many people online at once and it boots me and my friends.

So from what i can tell all i got was a copy paste without any resolution its been an entire day from posting this and the issue is still occurring in the past 20 minutes ive dced 3 times can i please get a resolution to my issue again i have contacted my ISP for the third time this week to see the issue my ISP is for the third time confirming the issue is connecting to the Final Fantasy servers. Ive even contacted them while the issue was occurring they traced my router and then the connection to the server and say the issue coming from the FFXIV server.

Could very well be NTT's network giving you trouble. Do you know how to run a tracerts to the FFXIV servers to see?

[Shinjisake]

I've been having this issue ever since the latest large patch appeared..... normal movement doesn't seem to be an issue, but dungeons, raids, trials, etc.... I get 90002 errors extremely frequent during encounters.... Gets VERY annoying. ISP Says everything is fine, PingPlotter shows the typical weak spots through Texas but otherwise everything runs fine. I have zero issues with any other game, videos, web, etc... Wireless/Wired makes no difference. Not a great experience .... All ports open, network settings reset, ran as Admin....
