Lag spikes and disconnects regularly after newest update

[imadbros]

Hello,

I've been having some pretty noticeable lag spikes and frequent disconnects since the update on 04/03/2018 when I am in the Palace of the Dead. A brief description of what I mean is that I'll notice the "disconnect" icon on my character name and then enemies will "teleport" as my connection tries to catch up. Other times I just disconnect without warning. Everything is completely fine and lag free and then I'm kicked to the character select screen.

Some system information:
- Platform: PC
- Any error codes or messages you receive upon disconnect: 90002
- Type of connection: wired to router and wired to modem, both are affected
- Other programs running while the game is playing: None
- Frequency at which disconnect occurs: Every 20 minutes or so.
- Where you are booted to after disconnect: Character Select screen
- Where in the game does this occur? Is there any pattern to the disconnects?: Palace of the Dead.
- Everything you have tried to resolve the issue: Restarting my PC, restarting my modem, ran a traceroute to see if there's noticeable drops.

I haven't had any issue before the patch and have ran Palace extensively just before the patch with 0 connection issues. There's been no hardware or software changes on my PC or within my network.

Thanks for your time.

Hello imadbros, Thank you for posting on the Final Fantasy XIV Technical Support Forums

The issue you are describing is most associated with interference with the game data. Most of the time, it results from certain security/privacy changes on Internet Explorer. Other times it occurs when an application that is running in the background is causing interference, such as Anti-virus software, firewalls, media players, web browsers, etc.

Please make sure all background applications (including anti-virus programs such as Norton, Kaspersky, Windows Defender, etc.) have been disabled and/or closed to minimize game interference.

Ensure that the latest version of Internet Explorer is installed on your PC (even if you don't use Internet Explorer), please do not use Edge as that is a different internet platform. Once Internet Explorer is up-to-date, please open the IE browser, open the "Tools", go to "Internet Options" and adjust the following settings:
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, please move the slider to the lowest possible settings or to "Allow All 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"
Go to the "Compatibility" tab, and change the compatibility mode to "Windows 7"
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"

If the suggestions provided above do not resolve the issue, then there is a communication error.
Check the following Port Ranges on your router/modem to ensure that the following Port Ranges have been opened/forwarded/triggered:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

Hope to be of assistance.
