My site was deployed and was waiting on DNS propagation for the SSL certification. I checked back a bit later and my site is now https enabled. I get the same warning from Chrome and when i click “Renew certificate” I get “mydomain.com doesn’t appear to be served by Netlify” even though I have added the nameservers to the domain. I would suggest Netlify not install certificates until everything is fully propagated so the user can indeed “Renew certificate”.
There’s no way to go back to just HTTP so i don’t know what to do here except hit “Renew certificate” throughout the day and hope(??)
UPDATE: I was able to “Renew certificate” but the warning persists. I’m afraid to keep renewing in fear of hitting the let’s encrypt request limit.
FINAL UPDATE: I guess it was a dns propagation thing. Checked my site after a few hours after clicking the Renew Certificate button and everything was good to go. No more browser warning.
