The source_address parameter of AsyncModbusTcpClient.__init__() is not passed to ModbusBaseClient.__init__(), so the default ("127.0.0.1", 0) is used, which causes an Invalid argument error when connecting to a non-local Modbus server.

  • Python: 3.10.9
  • OS: Ubuntu 22.04.2 LTS
  • Pymodbus: 3.4.0

Please test with current dev and confirm that it works.

We are planning to release 3.4.1 within a week, and if confirmed this will be included.
