[PC] Forza Horizon 4 - 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:

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...

Angamr,

I found 2 possible solutions/workarounds that you can try from
here:

Solution/Workaround A:

1. Click Start , type services.msc in Start search box and hit Enter.

2. Right-click the Peer Networking Grouping service and select Properties .

3. Check if the service is started; if not, right-click and select Start .

4. You may also set the Startup type to Automatic under Properties .

5. Click OK .

and restart the computer. if that dosent work. do this to.

. Run command Prompt as administrator

2. Type "netsh" and press enter

3. Type "int teredo" and press enter

4. Type "set state disabled" and press enter

5. Type "int ipv6" and press enter

6. Type "set teredo client" and press enter

Solution/Workaround B:

Set your DNS to 8.8.8.8 and 8.8.4.4 for primary and secondary

These were 2 that I found quickly looking through that thread. If neither of these solutions help, continue to read through that thread and see if there are any other workarounds that you can try. It seems like this is a widespread issue that is affecting
a lot of players.

Please let us know if any of those solutions work for you.
