Registering webhooks for private repositories fails, however it is successful for public repositories using the same access token for my account. I am able to clone the repository in the job, so I believe that my user access is properly configured, and all of the repositories are under my account, so I should have admin access. The access token does contain admin:repo_hook, and seems to be configured correctly based on the registration succeeding for the public repositories.
I enabled logging based on the recommendation of the Github plugin and see the following:

I renamed the repository in Github "project" to "project2" and then changed the URL in the job configuration, and when I saved the webhook was created on Github. I then deleted the webhook, renamed the project back to the original name, removed the 2 from the Jenkins config, and once it again it was able to create the webhooks when I saved.
It seems that something was in fact messed up with my project on Github and renaming it seems to have fixed it....
I created a new private repository with only a README.md and copied the failing job only replacing the git URL with the new project name and it successfully created the webhooks. I also copied the failing job and just ran it without success. This seems to me to point to an error on Github's side, not Jenkins.
"doublesharp" is a user account.
I'm still trying to debug on my end, and now I'm seeing strange behavior. I have 7 total jobs, with 4 public and 3 private. When I submitted this issue the 4 public repositories worked and all 3 private repositories were failing, however now only 1 private is failing and the others are successful. I manually deleted the webhook and verified that it was recreated by Jenkins when I saved the project configuration.
I don't see any meaningful differences between the configurations, so I wonder if maybe the issue is actually with Github?
Authentication error seems to be with Github even with proper Jenkins configuration. Some projects resolved the issue on their own, the remaining project was corrected by renaming on Github to an arbitrary value and then back to the original name.
