Why a Transfer Fails or Stalls
These issues usually do not come from one single cause. Common cases include:
- Temporary problems on the upstream cloud node
- The file is very hot and the platform is queueing tasks
- The upstream source triggers throttling or risk control
- Network congestion during a specific time period
Recommended Handling
- Wait for a while and sync the task again.
- If multiple routes are available, switch routes and retry.
- Avoid peak hours and resubmit later.
- If it fails repeatedly, keep the task information and contact support.
