I kinda knew what kind of ****show I was going to get for buying one of ubisofts games as they don't seem to be able to handle multiplayer at all, let alone that terrible uplay software yet here we are again.
I get this issue when trying to join my mates game through uplay. It launches the game and gets me to the main menu, that's it. Clicking the join button again gives me this ****.
My mate gets a varying degree of ******ation from the game too with **** like this
And the same one I get.
We managed to get the game working for like one hour when we tried coop for the first time and after that it has been just a never ending struggle against errors.
Yes, we've tried the suggested "fixes" with port forwarding and dns flushing and such to no avail.
So we managed to solve the issue and got our coop, just follow these steps.
1. Contact paypal if you paid for the game with them or your bank/credit card holder
2. Issue a chargeback on the grounds that Ubisoft has sold you a faulty product and refuses to fix it
3. Wait maybe a few days for paypal/your bank to handle the situation on their end
4. Get your money back
5. Buy something else that has coop but works instead.
