Blank page from Duet Web Control

[k3lag]

My printer has been working fine for months but suddenly Duet Web Control is just serving up a blank page.

I can ping the printer and I can print to it from Prusa Slicer but DWC won't come up.

I have tried it from multiple browsers and multiple computers.

The top of page banner says "Duet Web Control" so it's getting something.

I have tried rebooting the printer and it makes no difference.

Safari's developer mode is showing this:

@k3lag I suspect you're operating your printer in standalone mode, so I suggest you turn off your printer, take out the microSD card, and overwrite the files in /www with the files from DWC. If you aren't already on v3.4.5, it may be a good idea to upgrade the firmware as well.

@chrishamm You are correct regarding stand alone mode. It is a Duet2 Wifi. I'm not positive what version it's currently running but it's reasonably up to date.

I'll give your suggestion a try in a bit and report back. It's probably beyond time to do a backup and maybe switch to a new card anyway. I've been using this card since this Duet2 was new over 2 1/2 years ago.

@chrishamm That fixed it. SD Card failed. Fortunately I was able to get all the critical stuff off of it.

That is a good reminder to back it up more often.

It's running 3.4.2 but I'll upgrade it shortly.
