Hello there

After upgrading Flex 200 from firmware 5.20 to 5.30, our users cant sign in anymore.
Anyone get the samme error.


We are using RADIUS for Duo.
If we create a local test-user in the Flex200, its works.
But then our duo/2-factor not working

Solution is to run users on the "Local" So radius is not working anymore.

Accepted Solution

    We found it.

    They have made a change for concatenate auth, so its enabled by default.


    Works again.
    Case closed.

    Verify the paths and credentials for accessing from USG Flex 200 to Radius. Also, change log details for debugging if the appliance can:
    • contact the server
    • access the server
    • query the user
    • and the user data is provided back to the device

    Thanks for sharing the correction made for solving the issue @syraarpe.
    Thanks also for trusting the recheck of parameters. Sometimes the assumption "worked before" is the worst partner for problem solving. :-)

    Thanks for the issue report. COA should not be tick after firmware update.  I will report this issue internally.
