Dead Space 3 coop problem-Failed to join game

At first, download and install the latest version of Origin at www.origin.com/download (and make sure you have your Origin account ready as well)
Close the origin client and go directly to you origin folder  C:\Program Files\Origin Games. Run the origin.exe in this folder with a rightclick -> run as administrator. 

Try to deactivate your firewall/antivirus software, get sure that Origin.exe and DS3.exe is added to the whitelist of your protection software. Some firewalls are able to block applications even while disabled.

Check the online ports of your connection:
TCP: 80, 443, 9988, 20000-20100, 22990, 17502, 42127
UDP: 3659, 14000-14016, 22990-23006, 25200-25300
For specific instructions on how to open your ports, please visit http://www.portforward.com/ or contact your router manufacturer.

Please let us now, if this problem after this workaround still exist.

I got the same Problem, my friend got the same router like me (vodafone easybox 803), and we turned on the DMZ mode, its like we opened all ports.

If i do turn the game into public, strangers can join our games, but not my friend to me.

We turned all off, for example the firewall and the virenscan.

We got both the Microsoft Defender and Microsoft Essentials, my friend win 8 64 BIt, me Vista 64 Bit.

I think, its a bug with ur software and the vodafone router -.-

Can u fix this problem plz, all of my games are working, i can host everywhere with the activ DMZ modus.

My wife and I recently got Dead Space 3 after the hours of fixing the overlay then forwarding all ports and trying all manner of different suggested ways to join games without getting the "Failed to join" error I am still at an impass.

Another friend who used to play Dead Space 3 jumped on real quick and i Joined him instantly, so I am thinking the only thing that could be wrong is that we are both on the same router and that is somehow making the game decide it doesn't want to connect. 

Does anyone have any tips or help on how to fix this?

Hello!

Me and my friend are trying to play Dead Space 3 coop, but we have encountered serious problem "failed to join game". This problem comes up when i try to join him and even when he tries to join me. BUT there is no problem when we try quick match.We are immediately connected to other players with no problem, but when we try to join each other, there it is "failed to join game" . We have tried everything, what we knew (or we could find on google). We tried switching off the antivirus, firewall, updating the game, updating the origin, running origin as administrator, running deadspace3.exe as administrator, we tried opening these ports:

• TCP: 80, 443, 9988, 20000-20100, 22990, 17502, 42127
• UDP: 3659, 9999,14000-14016, 22990-23006, 25200-25300

I tried to look up this problem and i have find out that this problem is very common and very few were succesful in solving this problem (they solved it by using one of the methods i already tried)
I would be glad if you could help me with this problem

Thank you

I found the solution, it was quite easy when it actually showed up. One of the ports was the right one and you need UPnP for it to work. 

Follow this but type in this port instead 3659 into TCP.

It should work.

not working

Did you enter your PC Ip-address and not the one in the video ? If so:

Open CMD, type IPCONFIG and then read the line IPv4 : xxx.xxx.x.xx <---- This should be the right adress.

I made a mistake it should be UDP.   So change from TCP to UDP. Then it should work.
