Would mean that yyou have an SSL certificate already installed at your host/origin?
Yes, I have certbot installed, which takes care of my certificate installation
If so, can you please check what SSL option is enabled? Is it
Full SSL or any other?
In the SSL/TLS option page, I have the Flexible option enabled.
Regarding the redirection, was your WordPress install on HTTP or HTTPS and was it working on which one before you moved to Cloudflare?
My WordPress install hasn’t changed from before. The only change I have made was to use Cloudflare DNS instead of Aruba DNS, and every route was working as intended before. The installation was on HTTPS.
Always use HTTPS and
Automatic HTTPS redirection options enabled at your Cloudflare dashboard?
Both of those options are disabled in the CF dashboard.
Other case is where you would also need to rewrite your HTTP to HTTPS at your WordPress database
I don’t have any HTTPS problems, everything is running ok in that front, and I have no problems of mixed-content.
