Response 230: ReturnCode: 32755 (CustomAuth service error: Error)

I am stringing together Playfab, Opsive, and Photon.

I am using Playfab authentication as described:

This results in a success and I am setting the AuthValues as shown below:

private void AuthenticateWithPhoton(GetPhotonAuthenticationTokenResult obj)


var customAuth = new AuthenticationValues { AuthType = CustomAuthenticationType.Custom };

customAuth.AddAuthParameter("username", _playFabPlayerIdCache);   // expected by PlayFab custom auth service

customAuth.AddAuthParameter("token", obj.PhotonCustomAuthenticationToken);

PhotonNetwork.AuthValues = customAuth;


Then in the Photon.Realtime.LoadBalancingPeer the setting is applied:

opParameters[ParameterCode.ClientAuthenticationType] = (byte)authValues.AuthType;

if (!string.IsNullOrEmpty(authValues.AuthGetParameters))


opParameters[ParameterCode.ClientAuthenticationParams] = authValues.AuthGetParameters;


The result is "Response 230: ReturnCode: 32755 (CustomAuth service error: Error)".

I have tried to set opParameters[ParameterCode.UserId] but this did not change the result.

Found the issue.

I believe the following error indicates that Photon was not able to verify the customauth with the endpoint specified in Photon.

Response 230: ReturnCode: 32755 (CustomAuth service error: Error)

For me, the endpoint had a simple typo so was not valid. I updated and things started to work. Yay!
