Hi.

Please, I need your insight on this.

Problem:
HTTPS redirection is not working when it set using cPanel Redirects.

The generated rule looks like this:

Code:
RewriteEngine on
RewriteCond %{HTTPS} off
RewriteCond %{HTTP:X-Forwarded-SSL} off
RewriteCond %{HTTP_HOST} ^example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.example\.com$
RewriteRule ^(.*)$ "https\:\/\/example\.com\/$1" [R=301,L]
Temporary Solution:

For this to work, we remove: `RewriteCond %{HTTP:X-Forwarded-SSL} off` from the rule in .htaccess file.

Please, what could account for this?

Our assumption is that perhaps it is because Apache doesn’t have `X-Forwarded-SSL` variable and so cannot determine whether `RewriteCond %{HTTP:X-Forwarded-SSL}` is ON or OFF and thus give up.

Thanks a lot for your help!

Hi @MajorLancelot

I apologize for my delay in response to you. I was able to replicate this behavior and I subsequently opened an internal case on the matter CPANEL-22603

The only workaround I've found at this time is exactly what you noted as well - comment out the X-Forwarded-SSL line in the .htaccess.

I'll update this thread when there's more information on the internal case and/or once the issue is resolved.

Thanks!

Just encountered this issue on v74.0.4.

Aside from deleting the line manually, changing to "X-Forwarded-Proto: !https" as a conditition instead appears to work fine to take proxies into account. This is also the recommended syntax by Mozilla it appears.
