Server Connector from Desktop Client

It looks like you have figured out the problem, but for those who might be reading this topic, I’ll add a few instructions:

To use a Server repository on the Desktop:

Remember that when you use a connector from a Server-hosted repository on your Desktop, the connection to the remote system (such as a database) is done directly from your Desktop, not from the Server. This means there should be network connectivity between your Desktop and the remote system (it may require adding rules to the firewall in your operating system to permit that connectivity).

Each connector stored in a repository is just a bunch of connection settings. Only when a workflow is running, it obtains the necessary connection settings from the respective connector and establishes the actual connection. Such connection is established form the machine where the workflow is executed.
