3.5.0 RC3 cannot connect to DWC

[KP0005]

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

[KP0005]

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

[KP0005]

Screenshots obtained using Edge inside the windows vm

[KP0005]

I do not think it's the SD card

[KP0005]

Current theories are either a software issue, a hardware issue (I have accidentally shorted the mainboard for a few miliseconds with a fallen screw several years ago, long before this started happening) or some interaction with my network setup.

Due to being unable to run ethernet cables to this floor, I use an old wifi router with DD-WRT as a bridge. I have used it as such for several years now, and DWC did work.

Keeps happening for me too some times. Restarting the printer usually works, but it's for sure another issue that needs attention.

Like now, if i try to connect to the printer using my phone(chrome on android) it can't connect and gives the error "ERR_ADDRESS_UNREACHABLE".

Update:

reverting BOTH DWC and RRF to RC2 fixes the issue

[KP0005]

@KP0005 reverting DWC but NOT RRF does not fix the issue
