this is all very new to me so please bear with me.
I want to use the m5 stack on my sailboat as a display for my rudder pos and depth. Both values are being published over mqtt via node red.

When i run this uiflow everything works fine and the mqtt values are being displayed on the device. But when i press download to the device i get an error:

traceback (most recent call last: file "main.py" line 69, in <module>
file "main.py"line 52, setup
file "umqtt/simple.py", line 68, in connect
0SError: [Errno 118] EH0STUNREACH.

what am i doing wrong ? :)
Many thanks for any advice.
