An AJAX error has been reported.

  • Hello,
    I have just received my board (duet wifi with antenna) and was trying to connect to it.
    I have done all the steps in the "1.) Getting Connected to your Duet" and I have connected to DWC but I think there is a problem with this board. I still have the board connected with the USB cable for power. I have not powered it from the printer yet.
    When connected to DWC, I go to settings and then to configuration files, but it just writes "loading", and never loads the files to configure them.
    I then try to upload files and it gives me this error:

    "An AJAX error has been reported, so the current session has been terminated.
    Please check if your printer is still on and try to connect again.
    Error reason: Unknown message type or not authenticated"

    I have changed SD cards in case of it was damaged but still the same.
    What should I do?

    What versions of RepRapFirmware and DuetWebControl are you using?

  • Hi dc 42,

    As the DWC writes:
    "Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
    Firmware Version: 2.05.1 (2020-02-09b1)
    Web Interface Version: HTML: 1.11
    Web Interface by Christian Hammacher
    Licensed under the terms of the GPL v2"

    I do not know what DWC version I use. The standard I think. This oneis taken with print screen.


    Thanks in advance for any help.

    Please update your DWC version as it is incompatible with your firmware version.

    You may have to extract that zip file into your /www folder manually to get it up to date.

    @sigourosandreas, if you go to the Settings page you will find the DWC version displayed there. You can use version 1.22.6 or version 2.0.7.

  • I did what you said. It is working now.

    Thank you for the excellent support!!!
