About two months ago, I was told about a the new upload path for mods with a 200 MB size limit rather than cloudflare's 100 MB. I tested out the vtech setup with a 124 MB file soon after I heard about it, and it worked quite nicely.

However, when I tried again last night and this morning, it no longer worked. The upload would start and go on for several minutes, but it would stop without warning and purge the filename from the upload list.

Has something changed about the vtech upload method?

It should still work, nothing has changed on our side.
