What it means.
Cargo requires a connection to your 3D software in order to Install Plugins (see Basic Software Setup) and to Import Assets (see Download / Import).
Error 103 occurs when Cargo is able to connect to the plugin in your 3D Software, but encounters an error that is blocking communication.
How to fix it.
Step 1: Close your 3D Software, and open it again. Make sure the plugin is connected.
You can find guides on how to do this for each 3D software here:
Step 2: Restart Cargo.
Step 3: Try importing a different asset to see if the plugin connection is successful.
