If you only have a local certificate for an SSL connection and use the SSLOpt:

clientopt.SSLOpt{clientopt.SSLOpt

{    Insecure: true,    Enabled: false,    CaFile:  "/tmp/test.pem", }

 

 

It will fail with the following ""failed to find CERTIFICATE"" due to not having the 

ClientCertificateKeyFile defined.  I will put a PR out in the repository for what I did to fix.
