Upload failed

The file type does not match its extension.	The contents are not what the extension claims. Re-export the file.
This file is too large for the current upload limit.	Split the file or ask an administrator about the limit.
This file exceeds the available upload limit.	The destination is out of room. Remove files or choose another destination.

None of these are worth retrying unchanged.

The transfer broke

These are worth retrying as-is:

• The file transfer was interrupted.
• The upload completed, but we could not confirm the file.
• The file transfer finished, but the upload could not be finalized.
• We could not start this upload. Please try again.
• The uploaded file could not be verified. Please try again.
• The upload service took too long to respond.
• The upload service returned an unexpected response.

A large upload keeps its progress across a reload, so a retry after an interruption resumes rather than restarting. This queue item cannot be retried after the panel was reloaded. means that particular row lost its session: queue the file again.

• Open Details on the row and quote the reference identifier when you ask for help.
• Retry one file rather than the batch: a single Try again avoids re-uploading everything.
• If a whole batch fails the same way, the cause is the destination or your access, not the files.
