      Morning!
      Or, afternoon now, losing track of time with this issue!
      So, during calibration and tweaking a few days back I had to hit my emergency stop button and then was having serious issues trying to connect.
      I somehow got it stable again (serial in, M552 S0 M552 S1 M997 S1 etc) and enabled logging.

      I had reason to kit my emergency stop again today and have the same issues. I've spent a couple of hours trying to connect so now turning to the forums.
      When booting up DWC looks like its loading then will stall on the "connecting" bar that hovers over the GUI. The green "connection established" bar in the background shows up, times out and vanishes but the blue "connecting" bar will just sit there. This loops over and over.
      I also see the orange "HTTP Timeout" warning and, more interestingly, a red "HTTP: Failed to get file list" error. I remember last time getting "ISP busy" errors but haven't had any so far this time round.
      Occasionally I get a clean startup, usually after connecting via serial with main power off and Initiating M115 S0 and M115 S1.

      M122 reports back good connection, hovering around -32 to -34.

      === WiFi ===

      I'm running RRF 1.5.2, DWC is the latest (can't remember number from when I COULD see DWC) and pretty sure wifi server is latest too as came in the RRF 1.5.2 package.

      Here's the relevant from my SysLog:

      Look at how many "login succeeded" messages there are for my computer's local IP. Something's up and I don't know what or what more to try, at this point I can't really use my machine.
      If anyone has any advice or pointers I'd be very grateful, thanks!

        @SamanthaJaneyCake Please post your full config.g file so we can see how you have things setup. Also You mention several times using "M115 S0 M115 S1" do you really mean that or have you been using M552? M115 reports the current version of the firmware and other details M552 is used to enable and disable the WiFi module.

            Please excuse some of the comments in the config.g... I tweaked and tested a lot and reused code from another machine of mine so ought to go through and clean up the comments a bit...

            Also, since posting and getting a backup copy of the SD (just in case) the machine's been running seemingly fine and is an hour or so into a laser job. In all honesty the unpredictable nature of the issue is more concerning as those usually have a more hidden solution.

              Next time you have to do an e stop button, and have this connection issue again, can you try doing a full power cycle, and see if the problem remains.

                @Phaedrux will do! But… I can say it does remain because my E-stop isn’t hooked up to the duet but to the mains. In an emergency I want everything to stop. Full power cycle is on my list of standard troubleshooting approaches.

                I haven’t had any issues since my last post and the only thing that’s changed is that I’ve commented out the line declaring DWC needs a password.
