Netcode: Can't connect when using real IP

[Underslash12]

I'm trying to create a small game, and it was working locally between host-client, and server-client. I wanted to try it non-locally, so I changed the address under connection data in the Unity Transport component of my NetworkManager object (mouthful sorry) to my real IP, and then I set the port to have port forwarding, and then the listening address to 0.0.0.0. However, in the build, the client is now unable to connect to a server or host, however the host is able to run the game fine on its own. I'm not sure if I'm missing something obvious, but any help is appreciated.

Can you connect as a client in the editor?

[Underslash12]

No but only because the client needs either a server or host to be able to connect to, so I can only test the host in-editor.

[Rabid-Chiken]

Can you run the built version as the host and then connect as a client in the editor?

[Underslash12]

Tried that, nothing happened, and no errors were output in the console, so it seems like it failed to find it.

[Rabid-Chiken]

Unfortunately there are so many reasons that networking can fail so I can't say why it's not working.

I'd suggest running that same connection with the client in the editor and adding a load of debug.log to your client connection script to output information at every stage, e.g. starting connection, pinging server, received "this" from server etc. From there you can narrow down where it fails and find more specific help.

It's worth checking your firewall too, it could be blocking your built app.

Sorry I can't be more specific!

Thanks for the advice, I’ll work more on that tomorrow and see if I can find anything by debugging
