HTTPS, which is at the beginning of most web addresses today, means that the page is sent by the server with HyperText Transfer Protocol Secure or "secure hypertext transfer protocol". This means that the page is sent with http and is encrypted to prevent it from being read directly on the network. Initially reserved for the transfer of sensitive data, this approach is now generalised to all web pages. For users, this means that your exchanges with the site are encrypted.
Do not use the HTTP protocol, but only HTTPS for all resources of each page of the website.
Check that each page and page resource on the website uses HTTPS and not HTTP.
