How to Fix Adobe Document Cloud PDF Upload Stuck at 0 Percent
Question details
The user is trying to save a PDF document to the cloud, but the upload process remains stuck at 0 percent for an extended period and eventually fails with an error message.

- Product
- Adobe Document Cloud
- Device & OS
- not provided
- Scenario
- Uploading or syncing a saved PDF file to the online Document Cloud storage.
- Observed behavior
- The cloud save shortcut fails to initialize the upload properly, leaving the progress bar completely unresponsive at 0% until a connection timeout error appears.
Ensure your internet connection is stable and verify that your network firewall or antivirus software is not blocking access to PDF cloud services.
Use the 'Save As' Function Instead of the Cloud Shortcut
Bypassing the quick cloud shortcut and manually routing the file through the Save As menu can often refresh the connection and successfully upload the document.
Sometimes the quick save shortcut caches an old session token or fails to trigger the proper upload protocol. Using the manual Save As dialog forces the application to re-establish a connection with the Document Cloud servers.
Launch your PDF application and open the document that is failing to upload.
Navigate to the 'File' tab in the top-left corner of the window and click on 'Save As' from the dropdown menu.
Choose 'Document Cloud' from the list of save locations, select your desired folder, and click 'Save' to initiate the upload.

Upload via a Supported Web Browser
If the desktop application fails to connect, utilizing a web browser isolates the issue and provides an alternative way to upload your PDF.
Experience Fast PDF Cloud Sync with WPS Office

Frequently Asked Questions
Why does my PDF upload stay at 0 percent for so long?
An upload stuck at 0 percent usually points to a network connection issue rather than file size. It often happens when a firewall blocks the application from reaching the cloud servers, or if there is a temporary server outage on the provider's end.
Does file size affect how long a PDF takes to upload?
Yes, larger PDF files containing high-resolution images or hundreds of pages will take longer to upload. However, the progress bar should still gradually increase. If it remains strictly at 0%, the connection itself is failing.
How do I know if the cloud PDF service is down?
You can verify the status of the servers by visiting the official system status page of your service provider (such as the Adobe System Status page). If there is a reported outage for cloud storage or PDF services, you will need to wait until it is resolved.
Can outdated software cause cloud upload failures?
Absolutely. Using an outdated version of a PDF reader can lead to compatibility issues with updated cloud security protocols. Always ensure your application is updated to the latest version to maintain a secure and stable connection.
