ensure that you are able to connect to wmi as that is what the error is indicating and there is no error logic to address any failures.
Try this and see if it succeeds or fails

gwmi win32_Printer -ComputerName Server1

Thank you for your answer Jonathan! The connection to wmi works, it shows me a list with my printers. Any ideas?

The next step is to add some basic error handling logic to try and narrow down the issue.
This breaks your functions into two try groups to handle the initial connection to the remote system and then the code that uses the connection. Based on the error returned you will know which function is having the issue and which code block to look at.
