Connection interrupted, attempting to reconnect...

  • "Connection interrupted, attempting to reconnect. HTTP Request Timed Out"

    I've had my fair share of resolvable issues, usually brought on by myself, but I'm about to lose my mind with this one.

    Put simply, I get the error above (and a disconnect) randomly, frequently. I can barely get a file uploaded, if at all, before it disconnects. There are three other machines, all using duet 2 boards in the same area with no issues. Moving the machine around (EG, closer to wifi access point) does not appear to help.

    Any advice?

    EDIT: RRF3.1, DWC 2.0.7

    DWC 3.1.1 should be used with RRF3.1.1

  • @Veti Thanks, I actually thought I was on the most recent version! I will definitely update. With that said, all my machines are currently on the same versions and I only have this issue with one. I will update and report back, hopefully it helps.

  • I updated to 3.1.1 RRF3 Firmware (apparently this one was 3.0), then 3.1.1 DWC, and now cannot connect. I have followed normal connection steps, it simply times out. I used these instructions for installation:

    And installed this firmware:

    I used YAT to go through the reconnection process and everything is fine -- until I try to use DWC.

  • can you post the output of m122.

    try and move the wiring.

    As an aside, is there a better way to display or format that on this forum?

    I admit I'm not sure what you mean by move the wiring, but I took it literally and jingle jangled things around.

  • Well, I'm not sure if it was the jingle jangling (or perhaps an indicator of other hardware issues) but I changed nothing and it eventually connected.

    I haven't had enough time to see if it still has connectivity issues, but it was happening frequently enough that I should know soon.

    Anything I should be concerned with in the M122?

  • So far so good. It was disconnecting every minute or so before.

    There is a code formatting button looks like </> or you could use backticks, a single one for `inline` and three over and under multiple lines


    Also change the line ending in the terminal for propper display before formatting in forum

    Occasiobnally when updating from 3.0 to 3.1.1 the wifi server firmware will not successfully update. You might want to try re-flashing just the wifi server by sending M997 S1
