One of my domain (neatofest.com) has configured automatically to Flexible SSL, whether the other domains are automatically configured to Full SSL at the time of adding the domain to cloudflare.
Now, when I try to change the SLL from flexible to Full, it just redirects to 404. The domain is working fine on flexible SSL, both on http and https. I have also created the Page Rule to Always Use HTTPS, but all are in vain. Please help to configure force https.
