Connecting a client on the same machine as Photon self-hosted server with Public Static IP

Hello,

I am running a self-hosted Photon server on a machine with a static public IP.

I can connect with external clients to this server, and everything works fine.

When I try to connect a client on the same server machine it failes, with connection refused error.

I tried to use the public IP, and 127.0.0.1 and both failed.

How can I make this work, or is this not possible?

Thanks.
