Hello,

 

My friend and I are tyring to play RA3 Co-Op. Every time we invite each other, we get the error "The Host Has Left The game" when we accept.

 

We have turned WIndows firewalls off. We have tried DMZ on the router. UPnP is enabled. We've tried no IP address specified in network setttings as well as our own network Adapter IP's, and also forced Port of 16000 and then port forwarded on router (also tried leaving balnk).

 

Both C&C Online and RA3.exe set to run as admin.

 

Nothing seems to work.

 

I even have a VPN option on my router, so we tried via that VPN too to no avail.

 

We could always ping each other and stuff, and chat to each other in the menus once logged in.

 

Any ideas very welcome, we have been at it for hours.

 

He's on Win11 and I'm on Win10. We tried with and without the 'quick launch' .exe patch.

 

Thanks for reading

Humble Bump 

[Cervanthes]

that error mostly hangs together with NAT problems on the host machine
its a issue we just recently figured outa  fix for and are slowly implementing it is for the time being the resolvment of this issue a giant hit or miss 

we had good reports with using some specific VPN providers [disclaimer we are in no way sponsored or endorsed by any of them]

 

Privdao Free tier with a spit tunnel set up has allowed people to circumvent the issue 
Premium Proton VPN with Portforwarding and p2p to true has worked 80% of the time

 

you can adapt these two guides into a solution should you have any questions just ask away
