[PC FC 26 FIX] I found the SOLUTION !
Hello,
After trying various methods from the forum, nothing has ever really worked, or it worked for one match and then the solution stopped working.
I did some research on my own and tried disabling my PC's firewall.
1) Close FC 26 and the EA APP (or Steam if you play via Steam).
2) Simply type “Firewall” in your Windows search
3) Click on “Windows Defender Firewall with Advanced Security”
4) In the firewall window, click on the option at the bottom that appears in blue “Windows Defender Firewall Properties”
5) Logically, it will be set to “Enabled.” Simply select “Disabled” and apply.
6) Now you can test it. Start a rush, try to make an offside for example, and see if you get disconnected. Since I did this, I haven't been disconnected from any matches, even though since Thursday, I could hardly finish any matches, 9/10 i get DC
Let me know your feedback, whether it works for you or not. If it doesn't work for some of you, I may have another solution that has never been explained on the forum.
Enjoy the game
