Hi, @andresb. Our hosting won’t serve your site via HTTP only. It will only redirect to HTTPS if an HTTP request is made. There is no setting to enable this behavior. This is always what we do by default.
My best guess would be that time to live (TTL) values in your previous DNS records are causing your domain to sometimes be directed to a different service.
If that is the root cause, this will stop happening when the previous DNS record you created expire from DSN resolver caches.
Now, is it hypothetically possible our service returned an non-SSL response? Yes, it is possible but I consider it very unlikely.
If you do believe the response is coming from Netlify, please send us the x-nf-request-id HTTP response header which we send with all HTTP response.
There more information about this header here:
If that header isn’t available for any reason, please send the information it replaces (or as many of these details as possible). Those details are:
the complete URL requested
the IP address for the system making the request
the IP address for the CDN node that responded
the day of the request
the time of the request
the timezone the time is in
To summarize, I’m guessing that TTL values are causing you to still be redirected to another service sometimes. To find out for sure, please send the troubleshooting information above and we will be happy to take a closer look.
