Your Duet rejected the HTTP request: page not found

Hi, sorry I am having problems connecting to my duet. I can connect to it in the YAT terminal but when I try and connect to it using the web interface I get the error. I just deleted everything on the sd card and redid it using the file from the sd card tree but I still cannot connect to it. Am I doing something wrong?
-
That error message normally means that either the SD card cannot be read at all, or that the Duet Web Control files are not present in the right places within the /www folder.
To check that the SD card can be read, send M503 from YAT and it should list config.g. If that fails, send M39 to see whether the SD card is mounted, and M21 to try to mount it.

I had a similar problem. If no luck after following David's advice you may see if your router is configured correctly

The SD card is too big (64Gb). The maximum size of an SDHC card is 32Gb. Larger cards use a different storage system (SDXC).

Ah, well now I feel dumb; I got it to go. Thank you guys so much for your help.

No need to feel dumb, it's not at all obvious. The issue is that SDHC can use the FAT16 or FAT32 format (depending on capacity), whereas SDXC needs to use exFAT format, which requires paying a license fee to Microsoft. That's why open source software does not generally support exFAT or SDXC.
