I've done some further testing. First I recompiled OpenSSL with SSLv2 support. I received the same error when connecting to api.samurai.feefighters.com. I went back to the command line and tested more options to try and narrow down the problem. Here are the results:
openssl s_client -connect api.samurai.feefighters.com:443 -ssl2 Error (expected as remote server has disabled SSLv2) openssl s_client -connect api.samurai.feefighters.com:443 -ssl3 Works openssl s_client -connect api.samurai.feefighters.com:443 -tls1 Works openssl s_client -connect api.samurai.feefighters.com:443 -tls1_1 Error openssl s_client -connect api.samurai.feefighters.com:443 -tls1_2 Error openssl s_client -connect api.samurai.feefighters.com:443 -no_ssl2 Error openssl s_client -connect api.samurai.feefighters.com:443 -no_ssl3 Error openssl s_client -connect api.samurai.feefighters.com:443 -no_tls1 Error openssl s_client -connect api.samurai.feefighters.com:443 -no_tls1_1 Works openssl s_client -connect api.samurai.feefighters.com:443 -no_tls1_2 Error The second to last line demonstrates to me that the remote server is configured to prefer TLSv1.1, and somewhere there is a bug which is causing the connection to fail when using TLSv1.1. There is also an error when using TLSv1.2 but I am uncertain if the remote server supports TLSv1.2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1035558 Title: SSL handshake error when connecting to api.samurai.feefighters.com To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1035558/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
