Read the error message:
The network path was not found
That means that something that is trying to access a remote resource cannot find it, either because the URL is wrong, or the remote server is not available.
Start by checking all connection strings and so forth, and verify that the client computer has access to the remote device.
Sorry, but we can;t help you any further: we have no access to your code while it is running, or your system(s) - and you need both to work out the problem!
