Network plugin raised an exception

[Zygmunt Krynicki]

My system reports the following exception:

2021-03-27 22:18:00,617 ERROR Network plugin raised an exception.
Traceback (most recent call last):

    res = status_cmd.tostring()
AttributeError: 'array.array' object has no attribute 'tostring'

It seems related to array having tobytes, but not tostring on Python 3.9, as present in Hirsute.
