Question details
The user needs to resolve an issue where PDF documents fail to finish uploading to cloud storage and remain in a pending state indefinitely.
- Product
- Cloud Storage for PDF
- Device & OS
- not provided
- Scenario
- Uploading PDF files to a cloud storage service via a web browser to back up, share, or synchronize documents.
- Observed behavior
- The file upload process stalls, and the document remains pending for an extended period while the loading indicator continues to spin without completing.
Ensure you have a stable and active internet connection, and verify that the cloud service provider is not currently experiencing widespread server outages or maintenance.
Cancel the Stalled Upload and Retry
A temporary network timeout or interface glitch can cause an upload to hang. Canceling and restarting forces the browser to establish a fresh connection.
Cloud uploads rely on continuous data transmission. If a minor packet loss occurs, the web interface might fail to recognize the interruption, leaving the upload in a permanently spinning state. Manually terminating the process allows you to start over cleanly.
Locate the pending document in your cloud storage interface's upload queue. Click the 'Cancel' button or the 'X' icon next to the spinning loading indicator.
Press F5 or click the reload button on your web browser to refresh the page and clear any lingering temporary cache states.
Click the 'Upload' button again or drag and drop your PDF file back into the cloud storage window to initiate a new upload session.
Try an Alternative Web Browser
Browser-specific configurations, strict security extensions, or corrupted cache data can occasionally block the scripts required for cloud file transfers.

Frequently Asked Questions
Why do my PDF uploads to the cloud keep stalling at 99%?
Uploads can stall near completion if your browser or antivirus software blocks the final confirmation packet from the cloud server. Temporarily pausing web shields or clearing your browser cache often resolves this issue.
Can a very large PDF file size cause cloud upload issues?
Yes. Extremely large PDF files, especially those containing high-resolution images or interactive elements, might experience timeouts on slower network connections. Try compressing the PDF using a PDF editor before uploading.
Does clearing browser cookies help with stalled file uploads?
Yes, clearing cookies and cache can resolve authentication errors or corrupted session data that interfere with the upload process, forcing the cloud platform to establish a fresh and stable connection.
