[erlang-questions] TLS errors

Dear all,
I'm using SSL with Cowboy and I keep on getting these kind of errors in the
logs:

SSL: hello: tls_handshake.erl:167:Fatal error: insufficient security
SSL: hello: tls_handshake.erl:174:Fatal error: protocol version
SSL: certify: ssl_alert.erl:93:Fatal error: bad certificate
SSL: hello: tls_handshake.erl:118:Fatal error: inappropriate fallback
SSL: cipher: ssl_cipher.erl:292:Fatal error: bad record mac

I've started seeing those after I've upgraded to Erlang 18.0.2. This wasn't
happening in 17.5.

Has anyone seen this, and has clues for me to pinpoint what the problem is?
Also, is there anyway for me to recover the originating IP address?

Any help appreciated.

Thank you,
r.
