If you are experiencing a 404 error when trying to log into Honeycomb with SSO, you may already have an existing Honeycomb account that uses e-mail address and password as login credentials. To log in via SSO in this case, you must authenticate with your existing Honeycomb account before attempting to use SSO sign-in. Please follow the steps at https://docs.honeycomb.io/authentication-and-security/saml-sso/#404-with-sso-login-attempt to do so!
