DWC failure

[wouldstain]

Woke up to DWC not working at all this morning.
Getting blank page. Tried obvious stuff like rebooting.

Was running 3.4b7 all the way around.

Using Duet2Wifi w/ Duex

Built new SD card w/ clean config:

DWC 3.4.1
RRF 3.4.1

Issue persists across clean config and upgrade.
telnet to port 80 produces no output from DWC.

Able to print from SD card via paneldue.

Any help troubleshooting would be greatly appreciated.

Sounds like it's responding over USB and the PanelDue is working otherwise?

Can you send M122 and M98 P"config.g" and post the results?

Is the wifi module LED lit up?

Weirdest thing... It's back up now.

WiFi module has been up the whole time (it was responding to pings(ICMP))
Telnet to ports 23 and 80 were getting nothing

I did not connect directly to USB with my workstation and try to print.
I did put a file in the gcode directory on the SD card by hand and was able to print.

I did set up and connect an OctoPi as a possible work around and it did seem to be communicating but I had not had a chance to print with it.

I've been beating my head against my desk for the last 8 hours trying to get this sorted
and I walk away from my desk for few minutes and its back up.

I do not like issues that seem to resolve themselves in this way for obvious reasons.

It may have something to do with burning some sage and swinging a dead chicken around but.... That's dinner so it would have happened regardless.

Just for posterity:
