Hmm, so looks like we do have a bug that images.linuxcontainers.org is meant to be defined as 8443 in our config but isn't right now... not that it matters very much as the server listens on both ports identically.
I'd be surprised that your proxy actually needs the port to be included in the URL, it seems more likely that the issue is that port 443 is somehow treated differently than port 8443. Anyway, you can try this by doing: lxc remote add test https://images.linuxcontainers.org:443 lxc image list test: If that works, then your proxy is indeed somehow requiring the port to be passed, which would be the first time I see this. If that fails as with the others, then it does suggest that port 8443 is treated differently in your proxy and that's why this succeeds while communication over port 443 fails. -- 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
