splunk cloud trail http input ssl certificate error

[hzhou201]

I tried to setup logstash -> splunk cloud trail, but due to the ssl issue, i cannot forward, anyone has any idea?

you may open the link below and see: 

https://inputs.prd-p-ij0c3.splunkcloud.com:8088/

the logstash http output error -> ssl certificate name mis-match

I don't have option to disable the ssl.
