Hello @496988685,

I see no problem with the https version of your www subdomain.

Cheers,
sahsanu

hi @496988685

A) Please paste proper links (stop taking screenshots of text based things or pasting xxx links that go nowhere as it makes it longer for people to check and help you or may frustrate them)
B) Review HTTP vs HTTPs protocols. Your first page is requested via HTTP (this is a fundamental that you should understand before panicking and posting on forums)
C) as @sahsanu - SSL for use with the HTTPS protocol is confiugred well for your domain.
D) You can review this on this site https://www.ssllabs.com/ssltest/analyze.html?d=liorun.com&latest
E) I would also suggest some reading on TLS in general - apologies I don’t have any good links

Andrei

Hi @496988685,

I’m glad your certificates are working properly by now!

When you have a site available via HTTPS, it can also remain available by HTTP at the same time. This depends on how the web server is configured.

Right now, you have both http://www.liorun.com/ and https://www.liorun.com/ and both of them work (the first is an insecure connection, and the second is an insecure connection). This is a very common situation.

In most web browsers, if you just type in “www.liorun.com” without a protocol scheme (http:// or https://), the default protocol scheme is http:// and so the web browser will take you to the insecure version.

It is possible to configure the web server to send a 301 redirect which redirects people from one to the other. This is commonly done by people when they activate HTTPS on their web sites.

There is also a technology called HSTS where you can ask browsers to default to the HTTPS version instead of the HTTP version. If you’re very sure that your site will always be available in HTTPS and should be HTTPS-only, you can also use HSTS to tell browsers to remember this.
