[Self resolved] Unable to use the official FF14 Launcher

[Squadz]

Hi everyone,
I'm currently having multiple script error messge with the latest launcher.
"An error has occured in the script on this page"

- It didn't happen with the old launcher
- It's working fine with an alternative launcher XIVLauncher

Spoiler : The solution is at the bottom. Also SE Tech Support wasn't great in their troubleshooting.

I saw multiple players having a similar issues :
- Reddit 1
- Reddit 2

- You can also try Right-Clicking on the FFXIV launcher icon and select “Run as Administrator.” This option can also be set permanently by Right-Clicking on the FFXIV launcher icon, selecting Properties, then under the Compatibility tab, check the box that says “Run this program as an administrator” and clicking OK.

- Within Microsoft Edge, click the "Settings" option on the top right of the browser (under the three dots shown) and go to "Privacy, Search and Services" and go to the "Tracking Prevention" section. Make sure it is turned on and select the "Balanced" option.

- Additionally, if any settings have been changed overall, it is best to keep things at default which you can perform manually by using the "Reset Settings" option under the "Settings" tab. Lastly, please ensure that Microsoft Edge is up to date by using the "Settings" > "About Microsoft Edge" option near the bottom left.

- No interference with other applications such as Antivirus / Firewall

- 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

(Why bringing me to a paid software, when you can simply use telnet or netstat !? Those ports are also irrelevant)


My troubleshooting
- The official launcher is using built-in browser (QtWebEngine/Chrome or Edge), so it will mainly contact an https/443 address. I asked SE Tech Support more information about the built-in browser, of if there is any debug mode / logs : no answer :-/
- I ran Fiddler Classic to review the network trace, and bingo the FFXIV is working. (Fiddler act as a proxy).
- Once we know it's related to a proxy issue, I check the Edge settings.
- [Solution] : In Windows 11 -> Settings -> Network & internet -> Proxy -> disable "Automatically detect settings". Then the official laucnher should work.



for SE Dev : This should be considered as a defect/bug, because it's working fine with an alternative FF14 Launcher, and the official launcher should be able to handle the automatic proxy settings.
