: HTTP website returns 403.4 even when using Plesk Permanent SEO-safe 301 redirect from HTTP to HTTPS My domain has a valid and activated "Let's Encrypt!" certificate, and going to https://example.com

My domain has a valid and activated "Let's Encrypt!" certificate, and going to example.com works as it should and shows as being secure in the browser.

Through Plesk Onyx 17.5.3 I have activated the option Permanent SEO-safe 301 redirect from HTTP to HTTPS in Hosting Settings.

But when going to example.com, it shows a 403.4 Forbidden error and that I should use the https version of the website instead of redirecting to it.

In IIS Settings the option Require SSL/TLS must be turned off.


With it turned on, HTTP will always return a 403.4 Forbidden error.
With it turned off, the Permanent SEO-safe 301 redirect from HTTP to HTTPS option works, automatically rewriting the http address into a https address.
