Public IP/Photon Cloud not working

Hi everyone,

I might a bit of a newbie to the whole thing so please bear with me if I'm not making much sense.

I've created a turn-based MP game in Unity using PUN & Photon Server. I tested most features with Photon Server set to Local IP and everything works just fine.

Unfortunately, now I'd like to test everything on a device or on different PCs and I don't seem to be able to make it work.

If I select Photon Cloud (from Unity), I get the following message: TimeoutDisconnect while connecting to: ns.exitgames.com:5058. Check if the server is available.

If I choose self hosted and I choose "Public IP" from Photon Server it doesn't work - so I did a client test and saw that I receive a sort of error: OnOperationReturn: JoinGame failed: Return Code 32758 (Game does not exist). Disconnecting...

Not sure if I missed something.

Any help would be much appreciated.

Thanks!
