[PC] Multiplayer not working - IPsec issue

Hi guys,

I have been playing FH 4 in multiplayer for a week without any problem with my brother’s account on my computer.

I deciced to create my own Microsoft account and subscribed to Xbox Game pass to play.

First I had issues with synchronizing my new GamerTag but I solved that.

However I can’t play online, can’t see people’s paintings, auctions, etc. Nothing. I have been through the intro, but anyway from Automn on I should have been able to access the auctions and people’s paintings/car settings.

I have got this [Mod Edit - Abbreviated profanity, profanity and profanity that is disguised but still alludes to the words are not permitted - D] IPsec issue each time I am trying to connect to Horizon Life.

I didn’t touch anything in my router, Teredo is fine, NAT OK, connectivity OK, my Microsoft account OK to see people’s creation, I am not below 18 yo.

Again, I have been playing with another account for a week and it was perfect.

I uninstalled the game a couple of time, I reinstalled Windows 10 but still got this issue.

What’s wrong guys? Could anyone help me?

Please note that I have submitted a request to the support here but no reply yet.

I have never had any problem with Forza Horizon 3 and I even checked that one, it works great.

Before you ask, I have also tried all of the solutions from the internet and from previous posts in this forum, nothing worked.

Could it be an issue with my new account in conflict with the other one I used? I don’t think so as I reinstalled windows 2 days ago.

Please help me guys, I beg you.

Thanks in advance.
