GitHub Enterprise authentication with Grafana not working - github

Question

I try to set up GitHub authentication with Grafana. But I always receive this error:
{
"message": "API rate limit exceeded for 10.135.245.121. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)",
"documentation_url": "https://docs.github.com/enterprise/3.5/rest/overview/resources-in-the-rest-api#rate-limiting"
}
These are the logs after trying to sign in:
