Firefox throws "This Connection is Untrusted" when using hostname, but not when using IP address

I am remotely accessing a website which has iFrame in it. The website uses https, but iFrame tag has "src" pointing to a site using http only. However, when I remotely go to the site, iFrame shows the message below although the src" url is http only (there is no SSL certificate) when I use IP address (https://10.10.101.156:8006/apprecovery/admin/Core/Storage) in address bar instead of hostname (https://hostname:8006/apprecovery/admin):

This Connection is Untrusted

You have asked Firefox to connect securely to d37t50w1, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.

What Should I Do? If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

d37t50w1 uses an invalid security certificate.

The certificate is not trusted because it is self-signed.

(Error code: sec_error_ca_cert_invalid)

Why is it giving this when using hostname but not when IP address is using?

Corrected first para above: I am remotely accessing a website which has iFrame in it. The website uses https, but iFrame tag has "src" pointing to a site using http only. However, when I remotely go to the site, iFrame shows the message below although the "src" url is http only (there is no SSL certificate) when I use hostname address (https://<hostname>:8006/apprecovery/admin) in address bar. But I dont see the message in iFrame when I instead use IP Address (https://<IP Address>:8006/apprecovery/admin) to go to main website.
