        Good Evening,

        sorry for the late Reply, but i must work every Day so long..
        i now have commented out the Passwort in den config.g and rebooted my Duet 2 Wifi.
        Currently i run a testprint, and have a look, but until yet it looks good. I hope it stays that way!

        But if so, what i or we can do, so that i can use a Password Protection without any Errors?

          Did your password contain any special characters? Can you test a simple password?

            No it is only a lowercase Word, nothing special

              Good Morning!

              Since i have uncommented the Password Line in the config.g it seems to work?

              How can i report this as a Bug?

                @xenon2008 Consider it reported. Thanks.

                @chrishamm will be glad you were able to replicate it.

                  I'm sorry but I'm having trouble reproducing this issue. It's all working as expected on Windows (Firefox), Linux (Chromium), and OS X (Safari). Can you confirm that you are using RRF 3.2 and DuetWiFiServer 1.25?

                      Hi,

                      I'm running 3.2 on a Duet 3 Mini 5

                      I didn't have M551 so I added it and rebooted.

                      DWC came up, asked for PW, entered PW - no issues.

                      I removed M551 and rebooted.

                      DWC came up - no issues.

                      Using most recent Chrome.

                        @xenon2008 can you provide the actual config.g that provokes the error? Maybe there's a special character or something in there.

                            if you're concerned about sharing the password, sure. You can zip it up and email it to jason@duet3d.com

                              Hi, i am again!

                              Is it possible that its a PrusaSlicer issue?
                              I send the GCODE direct from PrusaSlicer to the Duet, and then i get this error if i click on "Jobs".

                              I also tried to give a simple Name like Test.gcode to Upload to the DWC, with no other caracters...

                                Hi i am again,

                                It really looks like the Error comes from PrusaSlicer....
                                I have now updated to the latest Version from PrusaSlicer (2.3.0) but it is the same.
                                If i upload the Gcode direct from the Slicer i get the Error on the Webinterface.
                                BUT if i see this right, i get this error only then when the Passwort for the DWC is active, without i get no error until yet.

                                So we have now to find out, if this is a PrusaSlicer or a DWC behavior.

                                Each time i upload a Gcode, also i have a dissconnect and a reconnect on the DWC, but without a Passwort dialog, even when the Password protection is enabled:

                                Hope this helps a little bit.

                                Kind Regards from Austria

                                  Hello together!

                                  Is there any Update?
                                  I made also a Thread on Github on the PrusaSlicer Page.

                                    I have just tested this. I find that if I upload from PrusaSlicer 2.3.0 and I have DWC open to the printer on the same PC, It reports "JSON.parse: unexpected character at line 1 column 1 of the JSON data", disconnects briefly, and reconnects immediately.

                                    I will look into the reason for the disconnection.

                                      This is fixed in DWC 3.2.1RC2.
