We have a setup where AES 7.1.7 monitoring nodes on pega 7.1.8. If we give the AES node url in the configuration settings it works fine. But if we setup AES node behind the Load Balancer and give the Load Balancer VIP name in the monitored node configuration, the monitored nodes are not able to send information to AES. AES server itself is accessible through the the browser but the monitored nodes logs say that they are not able to connect. Is AES behind a load balancer supported? What is workaround for this?
The 411 error indicates the content-header is missing. There must be a misconfiguration somewhere, where one device is configured to use chunked encoding, but the other are not. Perhaps try to disable chunked encoding on Nginx? I'm not familiar with Nginx.
