Have always been able to access county dept. of public health website but now get the following message:

SSL Not Supported Error 29 publichealth.lacounty.gov 2021-02-08 18:48:35 UTC

Am able to access website using IE and Chrome. Any suggestions about how to fix problem? Thanks.

被選擇的解決方法

I think that you need to access this website via HTTP and not via secure HTTPS, so Firefox forces https:// then you need to make an exception and load the site via http://.

I can't get it to work with HTTPS-Only enabled because the server appears to have a valid certificate installed (disabling HTO for this site doesn't work), so I need to disable this feature to be able to open the site via http://

With the newest Firefox, some Security Certificates have been disabled because of issues with new mal-ware. Can you check with the site on what Security Certificates they are using? (SSL and TSL encryption protocols)

Run your website through https://www.ssllabs.com/ and you can see all security issues that need to be fixed.
