cann't close osc server/py script

[high-solutions]

i can't seem to stop the threading server from within python.

I would like to make a osc command to stop the python script/receveing threading server but the server keeps running and responding

tried:
exit()
sys.exit()
subprocess.run(pkill "the python script")

only ctrl+c works if the script runs in the foreground, but i want to stop it with osc from wherever, also if it runs on the background
