    Astroneer "Failed to connect to host"


    Me and my brother got astroneer through PC Xbox Gamepass and we can't join each other. I've tried everything but nothing is working. Most people say it's NAT but I don't even have the option to find it anywhere. Can I have some help please

    :)

    Hi Zenuon
    Can you and your friend try to close and re-open the NAT ports in the router?

    Let me give you the ports:

    Port 88 (UDP)
    Port 3074 (UDP and TCP)
    Port 53 (UDP and TCP)
    Port 80 (TCP)
    Port 500 (UDP)
    Port 3544 (UDP)
    Port 4500 (UDP)

    Make sure to contact your Internet Service Provider for this.

    My friend is at his college and using his college's wifi, I don't know if he can change the NAT on that router.

    We have tried everything you have put in your response but nothing worked unfortunately. Is there anything else we can try? We are trying from fresh worlds too.
