Configuration Response Loss. AP and Zone Director on different subnet.

I am installing a 7025 on a different subnet of Zone Director. The Layer 3 connectivity is Ok. No firewall. The AP discovers the Zone Director. When the Zone Director starts provisioning of AP, the log send this message: AP[xxx] joins with uptime [1399] s and last disconnected reason [Configuration Response Loss]. The AP Status keeps on Provisioning. Any idea?

When you say "L3 connectivity is OK" - what tests did you perform? This sounds like a possible cabling/MTU issue.

I tested with the tools offered by AP (ping and traceroute) and zonedirector (ping).

If anyone is has an issue that seems related to 'configuration response loss' here is an example of an AP log prior to issue resolution.
The AP connection issue was resolved by resizing MTU both at remote site and ZD.
