Having FFXI-3101, can't even go to Character Selection screen

I've been having this error for 3 days now and I can't even reach the Character Selection screen because after accepting the terms of the game, I am greeted with the "Error Code: FFXI-3101 Transmission error with lobby sever".

"Have you tried restarting your modem router/PC/Steam/Windower/POL?"
Yes, all of them.

"Have you tried reinstalling the game?"
Yep.

"Is the opening CS disabled?"
It is.

"Is Client for Microsoft Networks installed?"
Yes, it is.

"Are the TCP: 25, 80, 110, 443 and 50000 - 65535 ports and UDP: 53 and 50000 - 65535 ports forwarded in your modem router and Windows Firewall?"
They sure are.

"Have you tried disabling the Firewall?"
Yes.

"Does your ISP blocks FFXI?"
No, they don't, I've questioned about this several times.

"Note that Proxy servers and satellite connections do not work correctly with FFXI."
I use Fiber, no Proxy.

"Have you tried using a VPN?"
Yep, Kaspersky VPN, with both Brazil, USA, Canada and Japan servers. Nothing.

"Have you tried using another connection or hotspot with your phone?"
Yep, same error.

"Have you tried using another computer?"
Yes, I have. Two, btw.

Therefore, I believe that the problem lies within my account. The last time I played FFXI I believe it was in February and I just can't accept the fact that I paid 70 Brazilian Real just to not be able to connect even to the darn Character Selection screen.

OK so on my THIRD attempt on a different PC, the game worked.

I believe there is something to do with Windows 11? Because all the other PCs were Windows 11.

Nope. Game works fine on windows 11. Running the latest bleeding edge PC with a ryzen 9 16 core 32 thread CPU and all the cool stuff. never had an issue.

It even worked fine on the beta releases of windows 11 on an unsupported CPU.

I used 3 different computers, two with Windows 11 and one with Arch Linux and Windows 10.
It even ran on Linux, but not on Windows 11.
Reverting to Windows 10 on my main computer fixed the error, so...

Soo... it only means you're missing some legacy component or other thing in the windows 11 install, something on the system isn't configured correctly, or you need to use compatibility mode to run the program (right click the program shortcut >properties > compatibility > "run this program in compatibility mode for" > choose different options until it works.

May also need to make sure it got allowed through windows firewall.

There's lots of variables. It's not simply "oh it works on this OS and not this one." I'm playing it on windows 11 right now. It works flawlessly.

sounds like firewall related
