I'm trying to connect to swift.ca-ns-1.clouda.ca:8443 via SSL. I can connect to this server from multiple other machines including other fresh 16.04.1 boxes (not on GCE), and I connect to it from other GCE instances that are not Ubuntu 16.04.1, but when I try connecting from any Ubuntu 16.04.1 GCE instance the SSL handshake fails. I've posted an example output from openssl below. Note that I can connect to every other SSL server I've tried. CloudA themselves couldn't figure it out. Any ideas?
% openssl s_client -connect swift.ca-ns-1.clouda.ca:8443 CONNECTED(00000003) write:errno=104 --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 305 bytes --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE No ALPN negotiated SSL-Session: Protocol : TLSv1.2 Cipher : 0000 Session-ID: Session-ID-ctx: Master-Key: Key-Arg : None PSK identity: None PSK identity hint: None SRP username: None Start Time: 1475846555 Timeout : 300 (sec) Verify return code: 0 (ok) ---
UPDATE: I've confirmed this only happens in the us-central1 zones (any subletter is also affected). Creating an instance in us-east1 works perfectly fine.
