Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

To clarify, this will happen immediately as you log in? Or is it while you are playing the game?

As for potential solutions, you may want to try some of the following:

The game will use the Internet Explorer web browser to connect to the internet. Open Internet Explorer, then open the "Tools" setting, 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"

Make sure your anti-virus/firewall has the appropriate exceptions for Final Fantasy XIV (you can temporarily disable them while you try to connect as well).

Check the following Port Ranges on your router/modem to ensure that the following Port Ranges have been opened:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040
Your ISP can open these ports for you.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!

It is while playing the game. I had no issues until patch 4.4
and how do you change the settings in microsoft Edge? I don't have explorer.

Hello BoazJochin. I apologize for the delay in my response.

The game will utilize Internet Explorer to connect to the internet. The IE browser should come installed on your PC if you have Windows 10. Try doing a search for it. Changing those settings on Microsoft Edge won't have the same effect unfortunately.
