Good Evening, I need a little help. I am new to this, so please forgive me if I have missed this. I tried to look through the posts before I submitted this.
Issue 2: I use Cloudflare to manage the actual websites I have in Hestia. So I have the websites created with WordPress and an SSL certificate here in Hestia, as well as mail setup through Hestia. If I set Cloudflare to flexible SSL, then I can access the webmail in Hestia webmail.domain.com , but I can’t access the website. If I set up the SSL to FULL in Cloudflare, I can access the site but not the webmail.
Yes, that is because when using Flexible mode, Cloudflare will use HTTPS between your device and Cloudflare servers, but then use regular HTTP on the back-side from Cloudflare to the webmail host.
When in Flexible mode, Cloudflare will use HTTP on the reverse proxy back-side to your website, and your website sees an incoming HTTP connection and tries to redirect Cloudflare to HTTPS. Cloudflare then sends another request in HTTP and your website again tries to redirect to HTTPS, this loop continues until the redirect limit is reached. Although in Flexible mode your browser says HTTPS, on the back-side Cloudflare is actually connecting to your website in HTTP.
