3.5.0 RC3 cannot connect to DWC

KP0005

Board: Maestro
Problem: I cannot access DWC. API connection through PrusaSlicer does work on the same IP.

DWC throws this error when attempting to connect:

 Failed to load resource: net::ERR_CONNECTION_REFUSED app.36984ccc.js

Reverting to DWC 3.5.0 RC2 does NOT seem to solve the issue.

The UI occasionally loads, but mangled (missing layout and color graphics). A few times it loaded fully, but I was unable to open text files for editing.

@KP0005
Tried:

reformatting SD card and putting a fresh copy of DWC on it
new network cable
reset network infrastructure
revert to RC2

Update:

It works on my phone but not laptop. Possibly an issue with the laptop? Maybe aspect ratios?

@KP0005 have you tried refreshing the page?

On laptop:
Straight after reboot, DWC loads correctly but fails to open text editor.

After one refresh, DWC loads without styling.

After another refresh, DWC fails to load.

@droftarts
Yes, many times, with results as described above

I borrowed another laptop and it does load the page correctly.

I tried a different browser on mine, still doesn't work

I was able to get a mangled UI through Firefox for long enough to get a diagnostic output:

Disabling firewall on my laptop did not help

Interesting...
DWC works on a Windows laptop
DWC works on an Android phone
DWC does NOT work on a linux laptop but does work in a Windows VM on that same linux laptop (edge browser)

KP0005

DWC dooes not load on a Kindle

KP0005

Works on chrome on linux but not Vivaldi

KP0005

Does not load on chromium

KP0005

Now it doesn't load in android anymore but still does inside that windows virtual machine

@KP0005 one for @chrishamm

More testing:
DWC is mangled in safari on macos
Doesn't load at all in Chrome on mac os

The issue has happened a few times before (including on stable builds months ago), but always resolved itself after a few minutes, hours or days.

I'm considering going to Klipper instead, since it's seriously impacting use.

@KP0005 can you run some diagnostics on the SD card? see https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card

I'll test rc3 on my Maestro when I get the chance.

Mangled DWC opened in OrcaSlicer. This is exactly how it displays on Mac and occasionally on my system

Screenshots obtained using Edge inside the windows vm

I do not think it's the SD card

Solved 3.5.0 RC3 cannot connect to DWC
