Current behavior

The connection between the openDAQ server and the openDAQ client is reset regularly.
Running python3 -m opendaq in the terminal displays relevant messages; for example:

$ python3 -m opendaq

Expected behavior

The connection should not reset if the network (in this case, a wired network) is stable.
