HELLO FROM ROMANIA. I PLAY HORIZON 4 EVERY DAY. I FINALLY FIND A 100% WORKING WAY TO FIX HORIZON 4 MULTIPLAYER ISSUES ON XBOX. I HAVE A TP-LINK ARCHER AX10 ROUTER, GIGABIT ISP CONNECTION. MY CONNECTION IS WIRED. THE TRICK IS NEXT: UNCHECK IPV6 FROM YOUR ROUTER SETTINGS. GO TO XBOX NETWORK SETTINGS. IPV6 MUST DISSAPEAR, IPV4 IS THE ONLY THING YOU MUST SEE THERE. THEN REACTIVATE IPV6 FROM YOUR ROUTER SETTINGS. BUT PAY ATTENTION: XBOX NETWORK SETTINGS MUST SEE AGAIN ONLY IPV4 ENABLED! YOU MUST REBOOT YOUR ROUTER AND YOUR XBOX CONSOLE IN THE SAME TIME. AFTER THAT ENABLE UPNP FROM YOUR ROUTER SETTINGS. AND THAT’S ALL YOU NEED TO DO TO PLAY WITHOUT PROBLEMS HORIZON 4 ONLINE! GOOD LUCK AND I WAIT YOUR CHALLENGES IN ONLINE EVENTS. MY NICKNAME: FASTIULY133. CHEERS!
It’s a good find and glad it’s worked for you…however, unfortunately, a lot of people aren’t able to access the network using IPV6. My internet provider only provides IPV4…fine for my Xbox as I have no issues, can’t play on PC due to Toredo issues (which wouldn’t be an issue with IPV6)
Hello. You should check Pc section with Teredo filtering. You can find on Youtube a quick tutorial for Windows 10. Maybe you can find a solution. Good luck!
Thanks for sharing ! Which online issue does it fix ? ( reach online, disconnect, long loading between races, crashes … )
By the way, you don’t need to use capital letters, rather the opposite.
