Solved Your Duet rejected the HTTP request

[Pyper]

I am trying to use the Duet 2 wifi for the first time. I have connected via YAT and it says I have firmware version 2.0. I need to upgrade but I can't connect via my web browser. The duet is on the wifi and I can see what the address is with M552. But when I go to the address it says "Your Duet rejected the HTTP request". How do I fix that?

@pyper Can you send M115 and copy the response from YAT so we know the exact firmware version?

You usually get that message when the files in the www folder on the SD card can't be read, either because they are missing or corrupt. Probably the easiest thing to do is put the SD card in your PC, delete the /www folder. Find the matching firmware version (from the M115 command) on Github: https://github.com/Duet3D/RepRapFirmware/releases

Find the 'DuetWebControl' zip file that matches your firmware. eg if you are using RRF 2.0, this file should work fine: https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/DuetWebControl-SD-2.0.7.zip

Download this, extract it on your PC, and copy the contents to the SD card, in a new /www folder. Then try it in your Duet. If that still doesn't work, have a look at the SD card troubleshooting: https://duet3d.dozuki.com/Wiki/SD_Card#Section_Troubleshooting_SD_Card_issues

@pyper said in Your Duet rejected the HTTP request:

But when I go to the address it says "Your Duet rejected the HTTP request"

What's the rest of the text on that page? RRF doesn't return that text by itself.

@dc42
The complete message is "Your Duet rejected the HTTP request: page not found"

Thank you for helping.

M115 returns "FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.0(RTOS) ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2018-06-05b3<LF>ok<LF>"

I downloaded the RRF2.0 link you posted, deleted the existing www folder, and created a new one with the DuetWebControl-SD-2.07.zip files.

I still get the same error. Not sure what is going on.

I formatted the SD card with the suggested utility to FAT32.

Arg!

@pyper that’s very old firmware on a Duet. Did you buy it recently? Where from?

What specification is the SD card you’re using? Please send M122 with the card in the Duet, and post the full response. Before you do that, remember to set the line ending to LF in YAT, or the response will be truncated and barely readable; see https://duet3d.dozuki.com/Guide/1.)+Getting+Connected+to+your+Duet/7#s7

Edit: also send

M20 P"/www"

to list the contents of the www folder.

I think they bought this awhile back but are only just now getting around to installing it.

Well, I keep trying to post the contents from those commands but it gets flagged as spam or something..

@pyper I’ve upvoted some of your posts which should give you enough reputation to post the long responses.

Try replacing the contents of /www on the SD card with the contents of this zip file: https://github.com/Duet3D/RepRapFirmware/releases/download/2.01/DuetWebControl-1.22.3.zip

Then see if you can reach the IP address.

If that works, Upload these 3 zip files, one at a time in the system tab in DWC. Don't extract them. Reboot after each. Use M115 to verify the firmware has been applied.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Duet2and3Firmware-3.2.2.zip
That will get your firmware and DWC up to date.

You can see the change logs here:
https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x

For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.
https://configtool.reprapfirmware.org/Start

Backup your existing config files in the sys folder in case you want to switch back to RRF3. IT’s easy to switch back and forth, just upload the zip file for the version you want and then upload your config files.

These documents will come in handy during the conversion.

@phaedrux
Success!
Thank you so much (all)!
I can confirm M115 returns 3.2.2 in YAT
Onward!

@pyper That's good to hear. Thinking about it, RRF 2.0 probably doesn't support DWC 2.0.7. My bad!
