The knowledge base does not yet contain a direct answer to how to fix Download Station when it is not working or not downloading.
What it does show is:
- Download Station is a web-based download application for BT, FTP, HTTP, NZB, FlashGet, QQDL, and eMule, and it can be launched from Main Menu or via http://_synology_server_ip_address_/download/ [12], [13].
- If download links keep failing, one suggested check is to try the file in a browser or another device to confirm the link is valid, and to check whether a file-hosting service has a free-user download limit [14].
- Older forums mention cases where Download Station stopped working after DSM updates or showed tasks stuck in waiting status, but those threads do not provide a general fix in the provided fragments [9], [10], [15], [16].
If you want, I can help you narrow it down based on the exact symptom, but the current knowledge base fragments do not contain a complete fix.
