FAQ

It is likely that you have misconfigured your self-hosted instance of Infisical. You should:
  • Check that you have set the CLIENT_ID_GITHUB_LOGIN, CLIENT_SECRET_GITHUB_LOGIN, AUTH_SECRET, and SITE_URL environment variables.
  • Check that the Authorization callback URL specified in GitHub matches the SITE_URL environment variable. For example, if the former is https://app.infisical.com/api/v1/sso/github then the latter should be https://app.infisical.com.
