The site is not available for some users on https from Cloudflare. How can this be?

Question

cloudflare

Friends, I have a https://suse.me service , a free ssl certificate from Cloudflare is installed on the site, some users began to complain that the site is not available via https, I could not reproduce this bug on any computer, everywhere opens as expected.
Checked with hosttracker:
https - 9 Fail, 31 Ok;
http - 1 Fail, 39 Ok
The site is indexed with https in all PSs. Can score on Cloudflare and set up a paid certificate for VPS, what would you advise me to do?

Answer 1

The browser really swears, for example, at https://suse.me/tags/media-player . Maybe it all depends on the browser. One quietly swears, and the other will refuse to load the site in order to avoid information leakage.

The connection to suse.me is encrypted using modern technology. However, this page contains other resources that are not safe. These resources can be viewed by a third party during data transfer, and can also be modified by an attacker to change the appearance of the page.
This connection uses the TLS 1.2 protocol.
The connection is encrypted and verified with AES_128_GCM. ECDHE_ECDSA is used as the key exchange mechanism.
