No web interface after upgrade from 1.16 to 1.18RC1

So, after being busy for a couple of months and moving to a new house, I was glad to see so many updates on the firmware in such a short time span. Thank you DC42 for your hard work.

So I just got my printer setup again and upgraded the firmware from 1.16 to 1.18RC1 and web interface to 1.15 (duet 0.85 ). The first issue I encounter is that I cannot reach the web interface any more. Network seems to be working fine, I can ping the Duet IP address, I can connect over serial with Repetier Host and send commands to the printer, I can see temperatures and all seems to be fine, I can even read the content of the gcode folder on the SD card.

I tried to delete the www folder and create a new one, extracted the content of the DuetWebControl-1.15.zip file inside it to make sure I have a fresh copy of the DWC and no old files inside, but still no luck.
M586 says HTTP enabled, FTP and Telnet disabled.

FIRMWARE_NAME: RepRapFirmware for Duet FIRMWARE_VERSION: 1.18RC1 ELECTRONICS: Duet 0.85 FIRMWARE_DATE: 2017-03-28

I'm an IT guy and I am usually able to fix such issues quite fast, but now I am lost...

Any help ?

Thanks !

There was one report of the web interface not working for someone using a Duet 0.6 and 1.18beta3. Sounds like a similar issue.

Please connect via USB, enable Network and Webserver debugging using M111, and report what debug messages you see when you try to load the web interface.

Hi David,

I actually did this yesterday evening. I enabled debugging (on all modules) and watched the console. Besides getting something like "module Network spinning, module Webserver spinning" and so forth from time to time, only when connecting to FTP I could see a lot of debugging information, but absolutely none when trying to access over http.

So I tried one more thing:
I left everything as it was, didn't touch the www folder, didn't touch the config files, just uploaded the 1.17e firmware instead (M997 S0 over telnet with the file uploaded over ftp in the sys folder).

Guess what, the web interface is back. So I suppose the 1.18RC1 has a small issue... but I surely don't know exactly what ...

I will stick to the 1.17e for now..

Regards,
Romeo

So you managed to enable FTP and Telnet in 1.18RC1, but not HTTP? This is getting even more strange.

Yes, I read that HTTP is enabled by default, FTP and TELNET being disabled. I enabled in the config all the protocols with M586 to check what's working and what's not.
Like I said, after switching to 1.17e without any other changes to the config, the web interface is back !

I've had another report of a similar instance at [www.duet3d.com]. I hope that may provide the information I need to track this issue down.

Please try version 1.18RC2.

Hi David,

Just tried the RC2 version and it seems that the issue is still present. What's strange is that there is absolutely no debugging info when I try to access the web interface, and there is something strange showing up on the M122 at the TCP stats:

How else can I help to track this down ?

Thanks for trying it, and for the report. Have you tried sending M552 S1?

Tried it, no luck so far:

ok

erial: M586
HTTP is enabled on port 80
FTP is enabled on port 21
TELNET is enabled on port 23

Strange thing: in RC1, ftp and telnet was still working, RC2 and RC2+1 nothing is working except ping reply. No debug info, just a few TCP dropped packets for every http, FTP or telnet connection attempt.
M552 S1 doesn't help at all, networking is enabled...

Thanks again. Please post your config.g file.

unromeo21, thank you for your patience.

Please can you try the new binary at [dl.dropboxusercontent.com]. If you still find you can't connect, please run M122 from USB and post the Network section of the diagnostic report here.

Thanks, looks like it thinks it doesn't have an IP address. That gives me something to investigate.

Thanks to your report I found the problem and fixed it in the 1.18 release.
