What it means

An Error 107 means there was an unexpected interruption during a download. This could indicate an internet connection dropout, computer or internet limitations or permission restrictions on your chosen download location.

Before moving on to the steps below, please restart your router, modem and computer.

  1. Unplug the router and modem's power cord from the outlet.

  2. Wait at least 15 seconds.

  3. Plug the power cords back in.

  4. Wait a few minutes for the router and modem to re-connect

How to fix it

Step 1: Check your internet connection and network security settings

While a fast internet speed is important, connection stability and bandwidth are just as important. Review the number of concurrent applications you have running and devices connected to the internet.

For frequent large file downloads (3D assets can range from a few MB to several GB per file), speeds of 50-100 Mbps are advisable, especially if you're multitasking with other internet-dependent tasks.

Sometimes your system's protection (Firewall, VPN, router settings, etc.) can affect installation of programs like Cargo or affect it's operations.

On the other hand, adding a VPN if you normally don't use one can stabilize an internet connection that's being throttled, is unstable, or is blocking your computer from download the assets

At this time, we're aware that those with Starlink ISP will not be able to use Cargo and must use an alternative ISP.

Review our documentation on network security and allowlisting URLs.

Step 2: Verify Cargo’s download location is valid and not encrypted

Log into Cargo and navigate to Account -> Software Settings to review your default or chosen Cargo download location.

You can update the download location from the default location.

Ensure that your drive's encryption is turned off in order for Cargo to successfully access downloaded files.

Step 3: Verify the download location has proper permissions

In order for Cargo to import assets into your 3D Software, the proper permissions must be set in your download folder.

How to Verify download location permissions

  1. In the Windows File Explorer, navigate to your chosen download location for Cargo.
    If you don't remember, or would like to change the download location, you can do so by logging into Cargo and clicking Account and viewing Software Settings.

  2. Open Properties: Right-click on the folder and select "Properties" from the context menu.

  3. Access the Security Tab: In the Properties window, go to the "Security" tab. This tab will show you the list of user accounts and groups that have permissions for the folder.

  4. Check Permissions:

    • Look at the list under "Group or user names:" to see which users and groups have access to the folder.

    • Click on a user or group to see the specific permissions granted to them in the box below labeled "Permissions for [User/Group]". This box shows permissions like Read, Write, Modify, etc.

  5. Modify Permissions (if necessary):

    • If you need to change permissions, you can click the "Edit" button. This will open another window where you can modify permissions.

    • Select the user or group whose permissions you want to change.

    • Check or uncheck the boxes under "Allow" or "Deny" to set the desired permissions.

    • Click "Apply" and then "OK" to save the changes.

  6. Check Cargo Permissions: Ensure that the user account under which Cargo runs is listed and has appropriate permissions.

  7. Apply Changes and Test: After setting the permissions, it's a good idea to test access by downloading and importing an asset from Cargo to see if it can now read from or write to the folder as expected.
