DWC not loading on iPad

MihaiDesigns

Duet Web Control not loading on iPad.

Running Duet 3 Mini5+ WiFi.
DWC is loading on Windows PC and on Android phone (same WiFi).
Other web pages are loading on the iPad.
The DWC interface appears to be loading, the title "Duet Web Control" shows up in the title bar, but the page content remains empty.
I tested on both Safari and Chrome with the same result.
The iPad is an old model but seems to be working fine.
Edit: I did try restarting the printer, the router, and the iPad.

I have no idea what to try next. I was hoping to use this iPad as a screen for the Duet-powered 3D printer.

It's an older iPad. I just upgraded to iOS 12.5.7. Still the same issue.

I think you may be running into the same problem as here:

@Phaedrux yep, this happened to me too. Stuck manjaro on an old laptop instead.

@Phaedrux thanks! I'm running iOS 12. I'll try downgrading the DWC.

This may cause other issues since the DWC version should match the RRF version as they are closely intertwined.

Here's a trick I use to keep using my old iPad 3:

Have a windows machine / VM that can access the DWC - I use Chrome
Enable Remote access on that machine
Install one of the few RDP clients that still run on the old iPad (I use iFreeRDP)
Follow these instructions to create a kiosk mode chrome session to DWC from the Windows Box:

?
Profit!

You could do VNC / Linux / Mac remote instead (so 1-3 would be different, I can advise if you go that route)

It works pretty well for me...

For sh!ts and giggles I just created a new instance on Lubunu with xrdp, of you dont want to pay the Windows tax.

After Lubuntu install, create a dedicated duet user.
sudo apt install xrdp
search & install google chrome ( I REALLY would like to use firefox, but the resource usage inevitably gets out of hand)
edit .xsession when logged in as duet :
add: exec /usr/bin/google-chrome --kiosk "http://192.168.1.8" (pease note 192.168.1.8 is MY duets IP address, yours will be different)

Frankly it looks better than the windows solution ...

Oh, enable the onscreen keyboard plugin if you ever want to enter gcode
