Hi,

I'm creating a watcher to check some values with an API Restful. It is failing with this error:

> [2018-02-22T19:07:00,941][ERROR][o.e.x.w.i.h.ExecutableHttpInput] [kibana] failed to execute [http] input for watch [_inlined_], reason [sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target]

The API is listening in HTTPS but it is self-signed. I don't find any attribute to skip the certificate verification: [HTTP Input | X-Pack for the Elastic Stack [6.2] | Elastic](https://www.elastic.co/guide/en/x-pack/current/input-http.html#http-input-attributes).

Any recommendations?.

Thanks.

You might get past this by installing your self-signed certs into your machine's certificate store. I have a test script that does this (also disables ipv6 to simplify things a bit for my case);

And I think you will have to use `https` if you're not already.

```auto
case $VMOS in
ubuntu)
  cp $QADIR/../certs/ca/ca.crt /usr/local/share/ca-certificates/
  cp $QADIR/../certs/elasticsearch/elasticsearch.crt /usr/local/share/ca-certificates/
  cp $QADIR/../certs/kibana/kibana.crt /usr/local/share/ca-certificates/
  update-ca-certificates

  echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf
  echo "net.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf
  echo "net.ipv6.conf.lo.disable_ipv6 = 1" >> /etc/sysctl.conf
  sysctl -p
  cat /proc/sys/net/ipv6/conf/all/disable_ipv6
  ;;
centos)
  # do we need sudo here?
  # sudo yum install -y ca-certificates
  sudo update-ca-trust force-enable
  cp $QADIR/../certs/ca/ca.crt /etc/pki/ca-trust/source/anchors/
  cp $QADIR/../certs/elasticsearch/elasticsearch.crt /etc/pki/ca-trust/source/anchors/
  cp $QADIR/../certs/kibana/kibana.crt /etc/pki/ca-trust/source/anchors/
  sudo update-ca-trust extract
  ;;
windows)
  certutil -addstore root $QADIR/../certs/ca/ca.crt
esac

```
