GitHub Desktop 1.0.1 Logged in but get authentication failure on push or pull

I am trying to use GitHub Desktop to access a repository that I have been using with Windows Git from Windows 10 64Bit. I am able to log in with GitHub Desktop but get an an authorization failure when I try to do a push or pull. The following is extracted from the log file:

2017-09-22T18:15:15.607Z - info: [ui] Executing fetch: git -c credential.helper= fetch --progress --prune origin (took 6.772s) 2017-09-22T18:15:15.617Z - error: [ui] git -c credential.helper= fetch --progress --prune origin exited with an unexpected code: 128. Permission denied (publickey). fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

(The error was parsed as 2: Authentication failed. You may not have permission to access the repository. Open options and verify that you’re signed in with an account that has permission to access this repository.)

I read over the documentation but did not see anything about setting up a public key similar to what I did for putty and ssh. Did I miss something?

@joshaber i’m not even going to bother. already uninstalled it. i’ll just do my stuff via browser.

For me it helped by simply logging out and in again (in File -> Options).
