WebHook works with Alerting but doesnt with watcher

Hi, Im trying to send webhooks to logstash with watcher, and Im getting this error

            "type" : "client_protocol_exception",
            "reason" : null,
            "caused_by" : {
              "type" : "protocol_exception",
              "reason" : "The server failed to respond with a valid HTTP response"

sending webhooks with Alerting works fine, this is my conector

But when I try with watcher it trows me the client_protocol_exception

Any idea on why is not working?

I'm not sure but based on the error message, it looks like there is a connectivity issue between watcher and the logstash instance.

Is it possible that you are using https (doesnt look like it, just to verify though)? Can you share the full exception?
