When RA3 came out I thought it was excellent. I wanted to play co-op with a friend so much, but I couldn't convince anyone else I knew at the time to spring $60 for the game. Never ended up playing co-op and forgot about the game for a few years.
Ra3 was on sale on steam for $15 a couple of years ago. I thought this was finally my time. I bought a couple of copies, only to learn the gamespy server had shut down. Bad luck. Still no co op for me.
In 2014, I heard about cnc-online. Set the game up, could see each other. So close. But then the game wouldn't connect. I heard it had something to do with a "natneg" server, so I guess I was SOL again.
18 months later, here we are. People are playing RA3. I must surely, FINALLY, be able to play the game. But when we try to click start:
"Connections are in progress, or connection problem detected. Please wait for the connection to finish, or kick the player who has the connection problem. Failed connection: 1 - 2"
Solution 1: If you got the game(s) through The Ultimate Collection bundle, DOWNLOAD THIS to prevent connection issues to people that don't have The Ultimate Collection. - Not applicable. Both copies are from steam.
Solution 2: User Elancore has posted several images of all the correct Generals and Zero Hour settings. Take a look at them here. - Not applicableSolution 3: Try adding C&C:Online to your Firewall exceptions. Use Google to find out how this is done. - Exceptions were made on both computers, and ultimately firewalls were shut off altogether
Solution 4: Do you have Hamachi, Tunngle or similar services installed? Try to disable their virtual network devices and shut them down. If it doesn't help, try uninstalling them and rebooting your computer. The IP address in the game's Options > Network settings must be your computer's LAN IP (e.g. 192.168.x.x or 10.x.x.x). - Neither computer has anything that would create a virtual network device. LAN IPs are set appropriately.Solution 5b: [RA3 ONLY] Removing the static port: If, when starting a game in RA3, your connection always times out, try the following: - Tried it. No dice.
Solution 6: Try opening your DMZ in your router settings. More information on how to do this can be found here.- -No Luck. Doesn't work.
I have also tried forwarding the port 16000, but no service seems to be running on it.
After all these years, I just want to play a co op game of RA3! Apologies if I have missed something, I have done my best to search the forums, and read the pinned threads.
