I noticed this some time yesterday that my WeatherPoly Node Server was offline. On the dashboard, I found it's displaying a notice "Failed to start weather monitoring service."

Looking at the log, I found "Web server failed to start: [Errno 48] Address already in use"

I haven't changed anything on my configuration and I confirmed the port is correctly configured as "8188"

I use this NS to receive information from my weewx software and also, haven't made any changes over there.

Via ssh, I found this in the port list which looks correct to me:

USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
polyglot python3.9  77205 5  tcp4   *:8188                *:*

What's the correct way to recover from this? Restarting the Node Server hasn't worked.

Thanks!

The node server is probably already running, just not connected to PG3.  

ps auxww | grep weatherstation.py  and see if it shows up in the list.  If so, then it needs to be killed before you can start it from PG3.   

That was it. Thanks!
