According to the troubleshooting page (Troubleshooting the Visual Experience Composer and Enhanced Experience Composer ), the fix is for my website domain (ISP) to whitelist the IPs for my region.
I am unsure where the whitelisting needs to happen.
my website has 2 webservers (AEM-based and hosted by Adobe Managed Services) and a load balancer in front (hosted in house). I have checked with our in-house team and no incoming/outgoing IPs are being blocked at the load balancer.
Can you please help? thanks!
ps. I have contacted Target support and they cannot tell me where to whitelist it as well. and while they have provided a workaround, it meant disabling EEC.
