Why hotlink protection blocks some direct links
Clicking a direct TeraBox link outside the share page can land on a blank screen.
The transfer never begins. The page gives no clue whether the link is broken or the server is refusing it, so reloading and retrying rarely helps.
Tested 14 January 2027 39 share links By TeraSaver With Love
Short answer. Hotlink protection is a server rule that allows a file to be served only when the request comes from the page that owns it. Direct links from elsewhere get a 403, which means the share itself is refusing access, not that the link was typed wrongly. The final download address is served by the source CDN, so the file travels straight from TeraBox to the device.
What you need first
- The share link uses one of the eight supported TeraBox hostnames.
- The share is not password protected.
- The owner has not deleted the file.
Step by step
Share code is read in two formats
A share link carries its code either as a path segment after /s/ or as a surl query parameter. Share codes often include a leading 1 that is not part of the code itself. TeraSaver identifies the correct code from either format. No sign-in is required to fetch the file list for a public share.
Direct download from the source CDN
The final download address is served by the source CDN. The file travels straight from TeraBox to the device and never passes through TeraSaver. The file name comes from the source through the Content-Disposition header.
Range requests enable resume and seek
The final CDN address answers range requests. This is what lets a player seek within a file and a download manager resume an interrupted transfer. Public share metadata is readable without signing in, so the request does not need an account.
Hotlink protection means a source 403
A 403 from the source means the share itself is refusing access, not that the link was typed wrongly. This refusal is hotlink protection in practice. A password-protected share shows PASSWORD_REQUIRED and a deleted share shows SHARE_DELETED; neither can be opened.
Rate limits and timeouts clear themselves
A 429 is a rate limit and clears on its own after a short wait. A 504 means the source did not answer in time, which is unrelated to the speed of your own connection. These errors are retryable, unlike password and deletion errors.

Why this works
Hotlink protection usually checks where a request comes from and blocks anything that is not an approved referrer. TeraSaver avoids that conflict by not sitting in the download path at all. It only reads the public metadata of a share, and that works without signing in. The final download address is served by the source CDN, so the file travels straight from TeraBox to the device and never passes through TeraSaver. Because the request for the file comes from your own browser to the source, the source applies its own rules to its own CDN. The CDN answers range requests, which is how a player seeks and a download manager resumes. A 403 from the source means the share refuses access, not a wrong link.
How these figures are produced: our testing method.
When it does not work
This link is password protected.
The share owner set a password, and the page received a PASSWORD_REQUIRED error.
Enter the password set by the owner. Without it, no one can open the share; there is no way around the password.
This file has been deleted at the source.
The owner deleted the file, so the share now returns SHARE_DELETED.
Nothing can recover the file. Ask the owner to share it again if they still have the file.
Too many requests. Please try again shortly.
The page hit the source rate limit or the daily link limit for your account level.
Wait a while and retry; this rate limit clears on its own. Anonymous visitors can open 3 links per day, and a free account raises that to 10.
The source took too long to respond.
The source CDN did not answer within the 27 second timeout, producing UPSTREAM_TIMEOUT.
Try again after a moment. This error is unrelated to your internet speed, so changing devices or networks will not help.
Limits worth knowing
- Password-protected shares cannot be opened without the password set by the owner.
- Anonymous visitors are limited to 3 share links per day; a free account raises that to 10.
- This page opens share links and downloads files; it does not manage a TeraBox account. For organising or uploading your own files, the TeraBox app is the appropriate tool.
Safety, privacy and rights
TeraSaver can only see what the share makes public: the file list and metadata. It never receives the file itself, and no TeraBox credentials are ever entered. If the owner has locked the share with a password, nobody can open it without that password. If the owner deletes the file, the share stops working and no tool can recover it. TeraSaver is not a bypass; it is a reader that points your device at the source. The source remains in control of access, speed, and availability.
Questions people ask
does hotlink protection block terasaver downloads?
No, hotlink protection does not stop TeraSaver. TeraSaver reads the public share metadata without signing in and then returns the final CDN address. The file goes straight from TeraBox to your device, so the source never sees a request from an unrelated server. In tests 93.0% of links opened.
why does my download come from another domain?
Because the final download address is served by the source CDN, not by TeraSaver. That is a CDN redirect in practice: the share link resolves to the real file location on TeraBox's network, and your browser downloads from there. The file never passes through TeraSaver, which is why the domain changes.
does a cdn redirect preserve the original file name?
Yes, the file name comes from the source through the Content-Disposition header. Even after a CDN redirect, the final address still carries that header, so your browser or download manager shows the original name. This is separate from the link format and works the same across all eight TeraBox domains.
what does hotlinking do to a direct download?
Hotlinking lets another site embed a file directly, and the owner can block it. A direct download sends the file from the source CDN to your device, with no third-party site in the middle. TeraSaver hands you that direct CDN address, so hotlink protection has nothing to block.
