sigmatcp 0.21

there is no communication with dac when started AS A SYSTEM SERVICE

  File "/usr/local/lib/python3.9/dist-packages/hifiberrydsp/client/sigmatcp.py", line 53, in connect
    self.socket.connect((self.ip, self.port))
ConnectionRefusedError: [Errno 111] Connection refused
 
WHEN sigamtcp system service are stopped and STARTED VIA CLI ( /usr/local/bin/sigmatcpserver -v ) no errors do show up, but still no communication (get-meta) possible.

does anybody know what is wrong here?

  Looks like the daemon isn't started correctly at all. Connection refused means that there is no server listening.
  
  As 0.21 was just released, this might be a bug in the new version (we only tested on HiFiBerryOS). Try the previous version 0.20 and check if this one is working.

  According to this log it has been installed. Why do you think otherwise?
