Description of the problem including expected versus actual behavior:

The websocket input returns an error message against a wss endpoint, that cannot be further debugged.

Steps to reproduce:

input {
  websocket {
    url => "wss://certstream.calidog.io/"    codec => "json_lines"
  }
}

output {
   stdout {
     codec => "rubydebug"
   }
}

Run this, the following appears in the log

[2021-07-21T15:52:41,003][WARN ][logstash.inputs.websocket][main][2101513c91f0271d0056eade918b8a849c8573e6fe681ce5ea226659f79a9eca] websocket input client threw exception, restarting {:exception=>#<OpenSSL::SSL::SSLError: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)>}

The stream can be read with tool like websocat

websocat -1 -E wss://certstream.calidog.io/
