Redirect to HTTPS is not working only for specific URL
Hi,
I host two sites, one is quebec3.com and the other is daishodesign.com. Both have been set up with SSL encryption using Let's Encrypt.
However, the one with daishodesign.com doesn't work; both HTTP and HTTPS are available. I don't want users to access any insecure URL so I set up an Nginx config file (/etc/nginx/site-available/...) properly. It should redirect users from HTTP to HTTPS, but it doesn't. The exact same configuration applies to quebec3.com and it perfectly works for it somehow.
I've been searching for a solution for about a few weeks, but I didn't find any until today. Today, I stopped googling with the keyword "Nginx", instead, I started including "Cloudflare" which hosts the domain name. Then I found something.
The page tells there's a configuration about HTTPS on Cloudflare. And I opened the page for daishodesign.com, and I found the root cause finally.
Always Use HTTPS was OFF!! Whereas it was ON for quebec3.com. This is it! I was totally biased my Nginx configuration was doing it wrong, but it was not! Cloudflare has some control over it, and I totally missed that.
So TIL; Check your domain registerer when it comes to redirecting as well as Nginx configuration.
