How to change the timeout variable?

[Dardanos-Aeolus]

When I am connected to a remote OPC-UA server via VPN,
I am able to connect directly with the opcua-asyncio library:
This work perfectly:

uasubscribe -u opc.tcp://192.168.180.210:4840 --timeout 30000 -n ns=4;i=63

However this does not work:

uasubscribe -u opc.tcp://192.168.180.210:4840 -n ns=4;i=63

Error:

    return self._uasocket.connect_socket(host, port)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\Users\...\Python312\site-packages\opcua\client\ua_client.py", line 155, in connect_socket
    sock = socket.create_connection((host, port), timeout=self.timeout)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\Program Files\...\Lib\socket.py", line 865, in create_connection
    raise exceptions[0]
  File "C:\Program Files\..\Lib\socket.py", line 850, in create_connection
    sock.connect(sa)
TimeoutError: timed out

This leads me to the conclusion that in my particular case the --timeout flag is crucial to use.

Question:
How do I enable --timeout with the GUI client?
At the moment I only get a TimeoutError when trying to connect with the GUI.

I tried to search for timeout in the source-code and dirty hard code it to a different value, but it didn't work.

Thanks for your help in advance.
