// std.net.curl.CurlException@std/net/curl.d(4402): SSL peer certificate or SSH
remote key was not OK on handle 56397DB61CE0

Exception is thrown when running on Ubuntu 21.10, but not when on 20.04.  As the same version of ca-certificates is installed on both set-ups, that might mean the issue arises due to a change between openssl 1.1.1f and 1.1.1l.

The only problematic thing I can see at a glance is that this site's certs aren't correctly installed.  SSLlabs reports:

- Chain issues: Incorrect order, Extra certs.
