systembus timeout signal not found

[yjeanrenaud]

I set up signal-cli on systembus.
I have on python script looking for incoming messages and wanted another to broadcast some.
But I get timeouts. seems the systembus object does not get found anymore:

Traceback (most recent call last):
File "pusher.py", line 100, in
send_signals(strNews)
File "pusher.py", line 58, in send_signals
signal.sendMessage(strNews, [], [strAllSubscribers])
File "/usr/local/lib/python3.7/dist-packages/pydbus/proxy_method.py", line 75, in call
0, timeout_to_glib(timeout), None).unpack()
gi.repository.GLib.Error: g-io-error-quark: GDBus.Error:org.asamk.Signal.Error.Failure: org.whispersystems.signalservice.api.push.exceptions.NotFoundException: Not found (36)

why is that? from what I understand, I could use the bus from more than one instance, no?
when I use the python cli to test, it works, even though it takes several seconds to do signal.sendMessage()
would you advice to change the timeout?
from pymodbus.constants import Defaults Defaults.Timeout = 100 or something higher?
