Why am I getting this error all the time when I try to join my friends Pod? Any solutions?

You said you had an error before, I got Errors when I tried to run it through a router, and also check your "nat2 type, which is your level of security, if you're on a router you might need to try something like adding yourself to a DMZ or, if you have the internet on your laptop/pc and a spare ethernet port, it might be worth sharing the connection or at least trying it, as if you're on wireless the thing that gets the stronger singal will obviously be better.

If non of the above applies, I dunno.
