History
Andy Green 06662a64fa LE-root-cert-update 
warmcat.com and libwebsockets.org use Let's Encrypt certificates... LE
have changed their CA signing arrangements and after 2021-01-12 (the
point I renewed the LE server certs and received one signed using the
new arrangements) it's required to trust new root certs for the examples
to connect to warmcat.com and libwebsockets.org.

https://letsencrypt.org/2020/09/17/new-root-and-intermediates.html

This updates the in-tree CA copies, the remote policies on warmcat.com
have also been updated.

Just goes to show for real client infrastructure, you need to run your own
CA (that doesn't have to be trusted by anything outside the clients)
where you can control the CA lifetime.

You can also test the client Basic Auth support against the http-server/minimal-http-server-basicauth example. In one console window run the server and in the other

$ lws-minimal-http-client -l --nossl --path /secret/index.html --user user --password password

The Basic Auth credentials for the test server are literally username "user" and password "password".
