1) The WHD ticket creation / update links are not redirecting to https and also not showing fqdn server host name.
2) HTTPS site is not secure error every time you open the WHD link.
3) is it possible to change WHD URL ?
You need to obtain an SSL certificate and install it in WHD. Decent documentation is here: Manage keys and certificates - SolarWinds Worldwide, LLC. Help and Support
Then enable HTTPS: Enable HTTPS in Web Help Desk - SolarWinds Worldwide, LLC. Help and Support
