Uploading how?

From the Web UI?

The Desktop client?

One of the mobile clients? (Sounds like maybe Android?)

Please provide client version and and the entries from your Nextcloud Server log from the time period of the upload.

from web ui, windows Edge, and server log :BadRequest
BadRequest, expect file size is 10485760 byte ,in fact is 0 form Nextcloud client and write to Nextcloud storge. perhaps there is problem in network or server write to storage.
i think that NC have changed upload mechanism in new version, and make upload files is not stable,when network situation is not good .
