Don't know when this became an issue, as I don't play much these days... but last time (couple weeks ago) I was able to join others' games. Now I cannot. People can join my host but I can't join theirs. Any suggestions??

This is pretty much all client stuff... NAT and similar. If other people can join those other games you are trying to join but you can't I'm not sure what could be going on.

ya... these are games that other people are in.

funny thing... i just reset my router and was able to join a game for a second, but it froze out so i left. was then unable to join it again, or any since.

u can host now so its all good

yes but i still can't join other games... this is a problem.

Did the problem happen after making router config changes to allow you to host? If so, have you tried reverting them to see if that fixes it as an additional data point?

no... until a couple days ago, i was able to both host and join other games... this is baffling me.
