x509: certificate signed by unknown authority - logstash

I created a logstash-forwarder crt and key on server with wild card as Common Name and on copying the certificate on forwarder I am getting the message 

Failed to tls handshake with 123.123.123.123 x509: certificate signed by unknown authority

Logstash Server 1.5.3
Logstash Forwarder 0.4.0

Solution

  • I would recommend to check your certificate carefully.

    Have you specified a plain wildcard CN? * does not match . so perhaps it won't match your domain. A proper wildcard CN should be something like *.example.com.

    Have you tried to verify your certificate with another software? e.g. a webserver? I suppose this is not a logstash issue.
