Whoops! Error loading Experience
Have installed vuforia Experience server on-premises,
Have checked.
- validated ES Url in vuforia studio -info.
- Mobile is in network with the host server.
- correct ES URL Set in mobile: " HTTP://<ipaddressofhost>:2019 "
- The firewall is off & ports are free & listening.
- ES is also pinging from the mobile.
In spite of all these checks I am getting an error: Whoops! Error loading Experience.
