Hi,
I setup a new cluster (two nodes) in active/active mode however only one node will process HTTP proxy traffic (configured transparent mode) at any time, which results in some devices not being able to access HTTP servers (I suspect that those failing are trying to be processed by the node refusing to serve HTTP traffic). If the HTTP proxy is turned off, connectivity is restored. No errors or fails are being recorded in the HTTP logs.
I checked the logs and found this:
