Xbox NAT-type connection and serverconnectivity blocked, tried every solution

This is not really a FH4 problem but a Xbox problem. It is just that fh4 uses the same connection as xbox live and party connection

Hello Ernesto,

We understand that you're experiencing connectivity issues on your Windows PC when accessing games through the Xbox app.

If you are experiencing the same issue after going over the solutions provided on our articles, it may be a possibility that some settings on your network or firewall settings are blocking the Xbox app to connect online.

To check the Firewall settings, follow the steps provided here:
Turn Windows Defender Firewall on or off

Also, we do suggest to open ports on the router or gatewayso provide the best connection to Xbox
LiveServers.

Open the following ports:

1. Port 88 (UDP)
   
2. Port 3074 (UDP and TCP)
   
3. Port 53 (UDP and TCP)
   
4. Port 80 (TCP)
   
5. Port 500 (UDP)
   
6. Port 3544 (UDP)
   
7. Port 4500 (UDP)
   
8. 
   

Check this support article on Network ports used by Xbox live.

Hope to hear back soon.

That's weird... on Nat Type I have "Moderate" too, but on Server Connectivity it says "Blocked". I tried every solutions featured
