Haha.

  • Is your machine date/time correct?

  • Can you try with tls instead of lwt_ssl?

      opam remove lwt_ssl
  opam install tls

  • What’s the output of

      opam list '*conduit*' '*tls*' '*ssl*'

OK. It recompiled conduit-lwt-unix. I regenerated the certificates just in case.

It works with tls but not with lwt_ssl.

Thanks for this. Still need to research the differences between them, and figure out how to use Curve25519 keys for the TLS connection.

I also noticed that the current implementation doesn’t complain about expired certificates, which seems like a problem.

I’ve added tls for now to the dependencies. I’ll open an issue.
