forza horizon 4 0x0000000 IPsec issue

If I was speculating, I'd think the issue is with your router or your internet connection (maybe your ISP has certain protocols or whatever interfering) but can't say for sure.

I did find a thread from a cuple of years ago which may be of help...I glanced through the first page and there are a couple of possible solutions to try:

Hi (Dennis299)

Do check out the IPsec error message guide on the Forza Motorsports
support page.

Hope this helps

Same I cant connect to Forza Online and support team is terrible and won't respond.

Ok, this one is going to seem like it is way out in left field but we will give it a shot, found it on the thread that I linked to earlier. It seemed to have worked for a few people repeatedly.

1. Go to your Settings on the PC for Time & Language.

2. Turn off the Auto set for the Time and Time Zone settings.

3. Turn the Auto set back on for both Time and Time Zone settings.

Try out your connection again. Let us know what happens!

All services are running an on-going:

- IP sec agent

- IP helper

- Peer2Peer networking

- Prnp protocol

And both related Xbox Live services in Manual as suggested.

No block regarding Teredo, NAT open, date and time are synchronized, windows firewall on, windows up to date.

Reseting my router didn't work, reinstalling W10 didn't work neither.

I checked corrupted files with SFC /scannow and everything is OK.

I am running out of ideas...
