    Hi,

    I just noticed my unit (Model A) stopped reporting to the network about a month ago.
    Currently running on a bench lab supply to rule out power supply issues (as that seems to be a common issue for others in the forum).

    When checking its IP, it does produce output (see example below), but when the wdt counter reaches 240, the unit reboots.

    I have checked that I can at least reach the stated server IP using traceroute, but not knowing what to look for in the communication I haven’t yet run Wireshark.

    Is there anything I can do to troubleshoot further?

    Sample output:

    uRADMonitor 110000BC
    type:1 hw:108 sw:126 SBM20
    radiation:12CPM
    temperature:23.75C

    voltage:378V
    duty:19%
    frequency:15.50kHz
    uptime:23s wdt:22s/240s

    ip:192.168.13.37
    server:66.228.41.43
    interval:60 http:0 0/0
    JSON [345]

    Unit seems ok , but traffic to the server is blocked.

    Do you ever get anything else than http:0 0/0 ? This means HTTP post return code (must be 200 to reset Watchdog), and x/y is number of successful packets (that got 200) / total packets attempted.

    Check the router security , it must be blocking the sensor’s traffic.
