I’ve used GarageSale for several years, so I’m very familiar with its operation. Tonight I created a new auction that repeatedly failed with the error message, “WebDAV: Could not upload file because of a username and password error.”
I had just refreshed GarageSale’s access token with eBay (which requires the user’s password) so I knew the issue was not likely to be my eBay password.
Here in this forum, I found only one topic containing “WebDAV,” and that issue (with the image server) was reported as resolved.
So, after 8 or 10 failed attempts, and because of the phrase “Could not upload file,” I finally decided to try switching from GarageSale’s picture service to eBay’s picture service — and with that change, my auction uploaded successfully.
Something is wrong with the GarageSale picture service.
(It would also be helpful if error messages were more specifically descriptive.)
