Strict-Transport-Security
The purpose of this header is to force all requests to go over HTTPS regardless of what is specified in the links etc. This header sets a TTL, and whilst TTL applies, the browser will only retrieve pages from the domain via HTTPS, no matter what the link or "address bar" says.
Examples of headers:
Strict-Transport-Security: max-age=31536000
Strict-Transport-Security: max-age=31536000; includeSubDomains
Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
Check that the header is set in the response.
The setting is cached in the browser so if you have made a setting it will be saved in the visitor's browser.
Referrer-Policy
A referrer that allows a website to control how much information the browser contains with navigation removed from a document. See https://scotthelme.co.uk/a-new-security-header-referrer-policy/
