If the error appears in every browser on the same machine, the problem is usually on that machine (clock, trust store, or local HTTPS interception) rather than every website. As asked, confirm whether it happens on many sites or only one — that answer directs the next steps. Good prompt from to check documentation, but here is a short, practical checklist to diagnose and fix it.

Quick diagnostic steps (in order):

  1. Verify system date and time are correct. TLS checks fail if the clock is far off.
  2. Try another device or network. If other devices work, the issue is local to the original machine.
  3. Visit a well-known HTTPS site and click the padlock to view the certificate details: note the issuer name and expiration. If the issuer looks like an antivirus, company proxy, or a private CA, that indicates local interception.
  4. Temporarily disable HTTPS/SSL scanning in any security software and retest.
  5. Update the OS and browsers so the trusted root certificate store is current.

If you operate the server, run a thorough test with the Qualys SSL Labs server test to catch missing intermediates or chain problems: Qualys SSL Labs SSL Server Test. If the error is Firefox-specific, see Mozilla’s troubleshooting guidance because Firefox can use its own certificate store: Mozilla support: Secure connection failed errors.

Do not add a permanent security exception unless you understand why the warning appears — accepting exceptions can expose credentials. If the above steps do not resolve it, include the site hostname plus the certificate issuer and expiration (or an SSL Labs report) when asking for more help so responders can pinpoint whether the fault is client-side, a proxy, or the server certificate chain.

it basically depends on the ssl certificates used by the websites. Do you get this in all the sites or only 1 site?
