File reached the maximum download limit
Mint, stream, or preview was refused because this file’s download count hit the per-file limit for the viewer’s tier. Same cap as File reached maximum number of downloads, different wording on the enforcement path.
Why this happens
assertPerFileDownloadLimitForViewer compares downloadCount to ul2_max_dnl_anon / _reg / _prem / _prem_pro.
Diagnose and fix
1. Raise Max downloads per file for that tier, or set 0 for unlimited.
2. Per-user override if needed.
3. Do not confuse with Max downloads per member (account-wide quota).
4. Refresh after saving limits.
