Problem with Duet Web Control

  • Good morning,
    I received my Duet Ethernet today and I wanted to follow the tutorial "Getting Connected to your Duet", I had the first connection between the card and my computer but after a few seconds Duet Web Control tells me that there is a connection problem and I no longer have any data displayed.
    Once the connection is lost, google displays an error page.
    Is there a solution?

    Thank you in advance for your answers

  • What browser? Are you using an IP or a name in the URL bar of that browser?

    When Duet Web is not connecting, can you ping the Duet IP address? By name (if applicable)?

  • I use Chrome and mine defaults to

  • administrators

    1. Please check whether you can ping the Duet after the connection is lost. Go to the command line on your PC and enter:


    1. Have you tried a different Ethernet cable?

    2. When the connection is lost, is there any activity on the yellow and green LEDs on the Ethernet socket?

  • Thank you for your answer.
    The browser is google chrome, I use the IP address for connection.
    The yellow light stays on constantly while the green light flashes at the beginning and then goes out after a few seconds.
    For the ethernet cable, I tried 3 different ones, I also tried on 2 different computers.
    Finally I tried different internet connections to try all the options.
    Did I forget something?
    Thanks again for your answers

    Sorry for the pictures in French 🙂

  • Your initial reply said Your screen shots are pinging Not only are those different addresses, in almost all home-network setups, they'd be on different subnets (192.168.1 vs. 192.168.0). Is that what you meant by "...tried different internet options...", that you changed your entire home network ?

    And, what is the most recent address of the printer?

  • thank you for your answer,

    What I meant was that I tried on a corporate network and it didn't work, so I tried on my home network and it didn't work either. So I changed my DUET IP address to and now DWT works fine.
    Thank you for your reactivity and your precise answers.


Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
