Grant rate limit per IP
Maximum times a visitor IP may call “Create download link” (/api/download/grant) in a rolling 10-minute window.
Where to find it
Admin → Settings → Files → Downloads → Grant rate limit per IP
Setting key: download_grant_rate_ip
Default often 40. The 10-minute window is fixed (not an admin field). Counts every attempt, including blocked ones. May also feed nginx edge limit rendering.
How it works
Lower for stricter anti-abuse. Raise for shared offices or heavy legitimate traffic.
Common problems
Shared NAT / office Wi‑Fi hits the cap
Many users, one IP. Raise the limit or space out grants.
