I have domain x.com
and I have subdomain sub1.x.com
x.com will work great with RUM >>is hosted by 3rd party
sub1.x.com I cannot get to function >> is on prem (will only support https)
https://thwack.solarwinds.com/product-forums/pingdom/i/feature-requests
says this is available for subdomains? but this documentation seems very old.
Can anyone provide some help?
