Mike.. This looks strange to me. The Radius IP address and shared secret used in the gateway is the same as with our 8 units A800 Tenor running live in the same VMGK.
This problem happens only after the VM was upgraded to 2.03. I already escalated this issue to sysmaster and they can not find any reason to isolate 0r captured logs considering the gateway is not hitting the VM either.
On the other hand quintum technical is saying that the unit did send the authentication message to the radius then it timed out due to no response from the RADIUS where this is evident as per logs attached.
What can you see about this. Did you encounter the same problem. My quintum has the latest firmware too.
Any help greatly appreciated.
