**Reddit wallpaper login fails with “invalid client ID” in DisplayFusion 12.1.1**

I am using DisplayFusion 12.1.1, and no beta version is currently available.

When I open the Reddit wallpaper-source settings and click **Login**, the browser opens Reddit but immediately displays:

“bad request
you sent an invalid request
invalid client id”

The error occurs before Reddit asks for my username, password, or authorization approval. It therefore appears that the OAuth client ID in the authorization request is no longer valid.

Can you confirm whether the DisplayFusion Reddit OAuth application or client registration is currently having a problem?
