[PC] "Unable to join session" error when joining friend's match or accepting friend's invite

Make sure you don't have networking issues by making sure ports are open for Garden warfare:

also make sure ports for Origin is open:

Some people were disabling Origin and that was causing issues.  Make sure everything is on becuase the invites are through Origin I think

My friend and I both have "enable origin in game" turned on. We also added the rules and ports to the firewall as suggested but it still doesn't work =/

The only consistent way I've found to join a friends game, is to join when their game is loading.  Right at that moment if you hit join, you should get in.

Tried that earlier, did not work for me. Thanks anyway 😕mileyfrustrated:

Same issue here. Joining my two friend keep me getting "unable to connect. check internet connection" and when I create the lobby, my 2 friends that try to join me keep getting that message until i'm getting that message too. This game is completely broken.

same error here although ports are open. multiplayer works for me...

i got the solution finally. you need to turn PVZGW in windowsfirewall to public and it work perfetcly

windows - system config - windowsfireall - advanced settings - incomming - and then turn pvz to public
