Common Output Upload Failures in PIX4Dcloud

Issue description / Cause

When uploading a file to PIX4Dcloud, the upload may hang or an error may appear in the upload window.
To upload files successfully, a stable connection to Pix4D and AWS servers is required. If this connection is interrupted or blocked, the upload cannot be completed.

Common causes include:

• Unstable or lost internet connection.

• Security restrictions (proxy, firewall, or network policies) blocking traffic to Pix4D or AWS servers.

• Browser extensions interfering with the upload process. Known extensions that may cause issues include:

  • Bitdefender Wallet

  • clearURLS

• File size exceeding supported limits.

Possible solutions / Checks

1. Check the internet connection

   • Verify that the internet connection is stable and has sufficient bandwidth.

   • If the connection is weak, switch to a stronger or more reliable network and retry the upload.

2. Review security restrictions

   • Ensure that firewalls, proxies, or security software are not blocking communication with Pix4D or AWS servers.

   • Configure the required exceptions as described in:
     Proxy / firewall configuration when working with PIX4Dcloud.

3. Check browser extensions

   • Try uploading the file using a different browser without extensions, or with extensions disabled.

   • To identify whether a browser extension is blocking the upload:

     1. Open the project in the browser where the issue occurs.

     2. Open the developer console (Ctrl + Shift + I or right-click and select Inspect).

     3. Select the Console tab.

     4. Start the file upload.

     5. Review any warnings shown in the console. These may reference the extension interfering with the upload.

     6. Disable the identified extension and retry the upload.

4. Verify file size and format

   • Confirm that the file meets PIX4Dcloud acceptance criteria.
