@dc42 This is almost a year old, but I am now having this issue. I cannot upload files to my Duet WiFi from PrusaSlicer any more, but was in the past. I have changed routers and seeing that 1.21 had issues with some routers, I'm thinking it may be similar. It also fails when using the Upload button in the web interface. It doesn't fail at the same location.
How do you do a WireShark trace?
