Use this help page to troubleshoot the most common problems when attempting to synchronize items or quantities with Inventoria or another instance of Copper.

Unable to connect to [host name] through port [port number].

Copper was unsuccessful in its attempt to connect to the server program. Confirm that the server program is running and has Web Access enabled. Verify that the host name entered into Copper is the correct host name or IP address of the computer which is running the server and that the port number entered into Copper matches the port number through which the server accepts web connections.

Connection rejected -- Application integration not enabled by [program name].

The application synchronization behavior is not enabled by any business in the server program. Complete the setup process for application synchronization in the Options dialog of the server program.

Connection rejected -- invalid authorization key.

The authorization key entered into this instance of Copper does not match that of the server. The authorization key is case sensitive and must exactly match the authorization key entered into the server program.

Quantity change failed -- invalid location name: [location name].

Copper is attempting to update quantities for an item at a location that does not exist in the server Inventoria program. The location name entered into Copper is not case sensitive but must otherwise match the name of one location in the server Inventoria.

Quantity change failed -- invalid item name: [item name].

Copper is attempting to update quantities for an item that does not exist in the server Inventoria program. The most likely cause of this error is that the item was created locally or deleted from the server Inventoria after the most recent item synchronization.
