I tracked down the authentication issue!

[GeekenDev]

The problem

The issue with authentication is related to the org level setting: oauth_application_policy.
By default this is enabled, thus blocking the authenticated action.
I was able to confirm this by enabling the dev tools inside of the application.

Temp. Workaround:
Navigate to your GitHub organization, locate Third-Party Access on the menu, click OAuth Application Policy.
Then click disable from the page you are currently on.

Thank you!

The repository does not seem to exist anymore. You may not have access, or it may have been deleted or renamed.

Thanks! I was running into this error on fetch. The workaround you mentioned resolved the issue.

Is there a way to allow GitHub Desktop instead of removing the restrictions altogether?
