⁉️ Problem?
So, I tried to login into the NetlifyCMS on my site and got this error message:
Git Gateway Error: Please ask your site administrator to reissue the Git Gateway token.
✅ Fix it!
I regenerated the GitHub API access token on app.netlify.com in Settings/Identity/Services/Git Gateway, and it fixed the problem.
Alternatively, feel free to use the link by replacing the *SITE-NAME*.
