I am not certain what exactly is triggering this error - but there are no redirects within my index.html?

Hi there,

Thanks for reaching out.

Render adds a default redirect from HTTP to HTTPS, although I’d assume Google would expect that behavior.

Does it give any more information other than “Redirect Error”? I’m not seeing any issues when hitting your domain in a browser, or through curl.

Thanks

Alan
