Your Connection Is Not Private

Connection Is Not Private
I get this error: "Your connection is not private." when trying to go to https://mail.startmail.com/ from Brave or Vivaldi browser I cannot use "Advanced" to push pass. (Windows 7 Pro 64Bit SP1). Does not matter if Startmail is listed in "Exceptions" on Vivaldi...(fresh install). Never had an issue on Brave before. No error with Waterfox on Windows 7 Pro 64Bit SP1 or using Brave on Linux Mint. When "fixes" listed on Google did not work, it pointed to Startmail. Tech at Startmail said: "This error is caused by a certificate issue which can happen on older browsers or older operating systems." Had me go to https://valid-isrgrootx1.letsencrypt.org/ If that did not work, manually install ISRG Root X1 & reboot. No joy. Tech reply is I would need to update my operating system to a newer version. Told him I did, to Linux Mint dual boot/Windows 7 5yrs ago. Main issue is Startmail not other sites. Any suggestions?

I figured it out. ISRG Root X1 is not an issue with Firefox/Waterfox as they do not rely on said certificates that old Windows 7 requires. Obviously not an issue with Linux as well.

As I understand certificates your browser is supposed to download and install certificates so that you can safely browse. When a browser tried to connect to a website (or even a local router page) your browser may issue a warning that there is a problem with the certificate. You can usually make an exception and connect to the website anyways.

I have to do this when I try to administer a RAID card, or a NAS or even a router all the time because these devices leverage a browser to display their configuration pages and the browser can't see a certificate to verify I am surfing to a safe place so I get the warning.

As I understand this a domain has to get a cert. from a signing authority and prove they are the real deal and the real owners of this domain. The CA issues a certificate to them but it does expire after a number of years so it has to be renewed and the powers that control this can also revoke a certificate when there is misuse.

I watch a lot of this guys podcast and I learn a ton about security:

To top all this off ...sometimes it's a simple as setting the correct date and time on your computer. That would cause trouble.
