Greetings HannibalCrossing,

I'm really sorry to hear that you've been experiencing connectivity issues. Error code 90006 is most associated with interference with the game data. It can be a result from certain security/privacy changes on the network. Other times, it occurs when an application running in the background causes interference, such as anti-virus software, firewalls, media players, web browsers, communications software, etc.

We would like to ask for the following information to get a better idea of the issue:

- Type of connection (wired or wireless):
- Has this been a long on-going issue or has this only been occurring very recently?:
- Frequency at which error occurs (If this occurs during specific hours, please provide the date(s), time and timezone):
- Are there other programs being used when running FFXIV?:
- What is the ISP and what region/country are you connecting from?:

We would also like to ask what have you tried so far to alleviate the issue:

Thank you for posting in the Final Fantasy XIV Technical Support Forums
