If you are using Chrome and seeing this type of screen (blank / incomplete with text missing from buttons etc.) when attempting to connect to your Horizon connection server administration console:
This behavior can be caused by a new security feature included in Horizon 7. The View Administration page in Horizon 7 checks the origin URL for the web request, and rejects the request if the URL is not https://localhost/admin or https://URL_used_in_Secure_Tunnel_URL_Field/admin. As detailed by VMware: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2144768
Follow the directions to disable checking the origin URL on the Horizon Connection Server VM.
