Might be of use (I have to look through the capture before I can upload it), but another developer here commented (if what he notes is true, then the TCP attempt wouldn't work behind an HTTP proxy, anyway. Does you environment block all non-proxied traffic?):

The HTTPS session connects to the remote port 443, while the TCP connects to the remote port 8080. I suspect the proxy is doing something that is causing the issue, but it's not as simple as the proxy outright blocking the connection. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575386 Title: Proxy issue with 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxd/+bug/1575386/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
