Server Disconnecting Clients - Wireshark Proof - Server sending FIN TCP flag- BUG

[Stathol]

I'll take your word for it that there wasn't any (permanent) packet loss in capture #1 and #3, but at the risk of being pedantic, I can't rule it out just from what you've shown. Only capture #2 shows the sequence number of the last client transmission prior to the server's FIN, ACK.

Edit: Actually, scratch that. I forgot that the ack number is the next expected sequence number, not the sequence number of the last received segment. None of your screenshots actually show how long its been since the server last ack'd one of your segments.

With that aside, you've indicated that you and your wife play on the same computer. So key questions:

• Do you use the same FFXIV client installation?
• Do you use one SE account with two different service accounts, or two completely separate SE accounts?
• Do you use the same local Windows user account?

To more fully isolate the problem, we need to eliminate these differences. We can do that either from your end or from your wife's end, and ideally we should try both.

For example, let's suppose you separate Windows accounts, separate SE accounts, and a single (presumably non-Steam in this case) FFXIV installation. Then:

Test A

1. Log in to your wife's Windows account.
2. Launch FFXIV and log in with your SE account.
3. Log in to the game with your Midgardsormr account.

Does the problem still persist? Do you still get a different socket endpoint than your wife? Make a fresh char on Midgardsormr. Same two questions.

Test B

1. Log in to your Windows account.
2. Launch FFXIV and log in with your wife's SE account.
3. Log in to the game with your wife's Midgardsormr account.

Same questions as test A. Make a new Midgardsormr char on her account and check that, too.

If you have a single SE account with different service accounts, the process will be slightly different, but hopefully you grasp the logic. We're want to determine whether the problem is bound to the client installation, the Windows user account (and all the environmental differences that entails), the SE account, or the service account.

It could also be very illuminating to reproduce the problem, and then immediately close and relaunch FFXIV using her credentials and character without touching anything else. Exact same Windows login session, exact same running processes, etc.
