We have install Secure Appliance before, but the reason we think it might caused by NSX firewall is
After we remove security appliance from Service Deployments:
- If we disable the NSX firewall in vCNS > Installation > Host Preparation > Firewall => restart browser(because browser might have cache) and connect to http server. We can connect successfully.
