I am running a Linux docker image on PlayFab Multiplayer Server. The clients are built with Unity for iOS/Android/Standalone/Nintendo Switch (not WebGL). I would like the clients to connect securely via WebSocket.
I assume in this case, I need to obtain a TLS certificate from sources like Let's Encrypt and then upload that certificate when creating a New Build on PlayFab Multiplayer Server.
How can I obtain this TLS certificate?
I believe the domain assigned to the PlayFab Multiplayer Server is in the format xxx.eastus.cloudapp.azure.com. However, since I don't own this domain, I think I can't obtain a certificate for it.
Thank you for your assistance!
