RefreshAccessToken() not working on EAuthTokenPlatformType.SteamClient

[Coodrag]

It returns error response AccessDenied.

Yes, I also encountered this problem.

Seems like a backend change that access token refreshes for SteamClient tokens are authenticated now.

I've updated the docs to reflect it: https://github.com/DoctorMcKay/node-steam-session?tab=readme-ov-file#refreshaccesstoken

According to the docs the CM must be authenticated. What does this mean? Does it mean only a valid Steam client (Steam Desktop Client) can be used? Can it be spoofed? 

I also tried to use k_EAuthTokenPlatformType_MobileApp but for some reason I get EResult 5 (k_EResultInvalidPassword) when I try to log in using the refresh token. Works when I switch back to SteamClient but then I can't refresh the token

[Dr. McKay]

It means you need to have an established connection to a CM (the same servers the Steam client logs into) in order to refresh the token. You can use steam-user to do this if you want.

What do you mean by "log in using the refresh token"?
