When using the NSX-V load balancer in front of the vRealize Operations Manager cluster you may want the URL to automatically redirect to the HTTPS login page.
If you do not configure this the user will need to insert the https field in front of the URL/IP Address. Similar setting is also required in a HAProxy configuration to ensure the redirect works properly. You must configure application profiles and virtual servers for HTTPS redirect.
Ensure that you are using the HTTPS URLs in a correct manner.
