What the error probably means
Paste the exact message. I’ll translate it into something useful.
Upload errors are often vague
A message that only says “upload failed” can hide several very different causes. Ninjitzu tries to separate the symptom from the rule.
Look for unsupported, file type, extension, PDF, JPG, or PNG.
Password, encryption, page count, orientation, or damaged PDF structure may matter.
Timeout, server error, unavailable, or try again later may point away from the file itself.

Upload error is a generic message. The actual cause may be size, type, page count, encryption, filename rules, connection issues, or a portal-side problem.
Should I paste the exact error message?
Yes. The exact wording often contains clues that identify the real upload rule.
Can Ninjitzu diagnose errors without uploading my file?
