We're using Github Pages with Cloudflare in front of it for TLS. I can't seem to get the root domain (http://trailofbits.com ) over TLS without breaking mail delivery. Does anyone know the right way to configure GH Pages, Cloudflare and G Suite together?pic.twitter.com/wnsGlN0cDp
Behavior today: http://*.trailofbits.com -> redirs to www https://www.trailofbits.com -> correct https://trailofbits.com -> cert error If I play with the A records, email delivery to http://trailofbits.com has stopped in the past.
Just now, I transferred the entire domain from Cloudflare to DNSimple DNS servers, changed it so the apex is configured via ALIAS instead of A records, and enabled the Enforce HTTPS option on Github Pages. Let's wait a few minutes to see what happens...
I don't follow either. Why would changing your A record for http://trailofbits.com affect your MX record when your MX is http://x.googlemail.com ? The domain doesn't specify DKIM, and SPF is rather straightforward.
A records still get referenced, even in the presence of MX records. DKIM, SPF, and DMARC are all turned on outside the screenshot.
GitHub pages supports HTTPS out-of-the-box now for custom domains. Perhaps that would be more straight forward to enable? https://blog.github.com/2018-05-01-github-pages-custom-domains-https/ …
“Breaking mail delivery” makes me jump to wonder of you are trying to CNAME the apex domain or not. I’m not an expert, but my understanding is that using a CNAME on an apec domain can result in funkiness.
Have you turned on CNAME flattening?
Yeah, what @cktricky and @vcsjones said, put your energy into getting your domain setup to ghpages' liking, then get it native from ghpages and @letsencrypt
