Random Disconnect (900002)

Hi,

I’ve been looking into a networking issue that’s causing FF14 to disconnect randomly. We have three people in the house playing at the same time, all 3 systems disconnect at the same time.

I’ve verified that IE is configured correct, there are no Anti-Virus alerts blocking network traffic, and the TCP ports are correctly open.

Examining the hops to the Elemental Datacenter (124.150.157.158) there appears to be an issue that emanates from that IP address.

Hop 7 apparently is OK. PingPlotter states that packet loss on a hop is OK if the destination is OK (https://www.pingman.com/kb/5). I’ve confirmed this, plenty of packet loss on that hop and FF14 works fine. My ISPs networking engineer I contacted also stated packet loss on a intermediary hop is OK as long as the final hop is working.

It appears that the packet loss that matters appears within the Square-Enix network. Below is the start of a failure.

I believe the 219117.144.x addresses belong to Square-Enix.

It then cascades from there:

I then get disconnected a few seconds later. By the time I fully close FF14 and restart, the route is behaving again.

This has been happening multiple times today and has happened multiple times in the past.

Can I please get assistance with this.

Thank you

Good afternoon and thank you for visiting the Final Fantasy XIV Technical Support Forums.

Do you experience any disconnections when connecting directly to the router?

Hi Dynratygus,

Apologies, I should of mentioned that. Two of the systems are directly connected to the router by gigabit cables and the third is using Wi-Fi. The results are the same; all three systems disconnect at the same time and I see PL emanating from the SE IP addresses.

Regards.

Good luck getting their help! I've sent logs from Wireshark showing SE servers sending me random TCP FIN flags disconnecting me for no reason, packet loss on the SE server side, Windows TCP process logs, etc, proving it is a SE issue.

I get disconnected every few min for the last 3 months, and they haven't done anything, or even admit this is an issue. They keep telling me it is a network/PC/routing issue, even though my wife plays on the same computers, same network, and has same routing path. I've gotten disconnected hundreds of times, she has never gotten disconnected once.

I've lost 3 months of gameplay, and cant do any raiding, dungeons, even crafting without nonstop disconnects.
