Connection psychopy and brainvision remote control server

Dear all,

we try to connect a Laptop with Psychopy and a PC with Brainvision to send triggers. Unfortunately, we are having problems with the network connection and have no idea where the fault could lie.
IP addresses are correct, cables have been replaced and firewalls are deactivated. The error message remains the same:

File “D:\TRIAL BRAINVISION CODE_lastrun.py”, line 42, in
rcs = brainproducts.RemoteControlServer(host=“192.168.1.1”, port=6700, timeout=1.0, testMode=False)
File “C:\Users\Experimental Laptop\AppData\Roaming\psychopy3\packages\psychopy-brainproducts\psychopy_brainproducts\brainproducts.py”, line 126, in init
raise RuntimeError(msg)
RuntimeError: Could not connect to RCS at 192.168.1.1:6700. Make sure the Remote Control Server software is running and set to “Connect”
