 https://chiselapp.com/ is a site which serves fossil repositories. I
 noticed that one of my repositories was failing to update with a
 certificate error.

 It failed on FreeBSD 12.2, El Capitan and Big Sur, so it is most likely an
 upstream problem. chiselapp.com uses Lets Encrypt as its root certificate
 provider  I tried accessing the site with Google Chrome and found no
 problems with the certificate chain.

 Here's the diagnostics from curl -v

 curl failed to verify the legitimacy of the server and therefore could not
 establish a secure connection to it. To learn more about this situation
