FortiAuthenticator: Radius losing connection from AP Huawei

[deraldo]

Hi, Guys.

I'm with a problem: the Huawei Access Point is disconnecting of FAC. The log says connection lost, and reconnect all times. The auth work fine, but the AP is disconnecting every time.

Hi @deraldo ,

Disconnects can happen for various reasons. 

From the screenshot provided i see different error " cannot get request arrival time "

In order to isolate further you can take a packet capture on the FortiAuthenticator.
There you can investigate further timings of the send and received packets and see if there is any delay caused.

Hi @deraldo ,

Additionally is there any Firewall in the middle? If Yes PCAP on all nodes might be useful?
Also check the time/NTP on all nodes involved in the flow.
