I'm using PlayFab and Photon together and everything worked fine yesterday. I just suddenly can't create room today. I have logged in with PlayFab and PUN, but I get the error when creating a room:
[Photon]Failed created room.  Failed to create game on https://mytitleid.playfablogic.com/webhook/1/prod/3DS36XKQCF7FD378R3SRXBDTNCT6GYNGCOGPW67E9FJCZK9UX6/RoomCreated? : Unexpected character encountered while parsing value: . Path '', line 0, position 0.
Does any know what this means and how I can fix it?
