All,
So I in my personl lab I setup Splunk and exposed 8089 and the mobile app worked perfectly. I went to go try the same using my POC cloud instance and I get "Sign in Failed - Cannot Acces the Splunk Web Port".
Hitting
http://mycloud.splunkcloud.com:8089
Tried 443 too just in case, no luck. Is there something special I need to do for this?
