PC browser loses connection to Cumulus on Pi, why

[Dublin-Bay-Prawn]

I have recently got CumulusMX running on a Pi2. Data is being collected from the Fine Offset weather station stored and sent to Wunderground.

If I re-start the Pi whilst the PC is running, I can access the Cumulus Dashboard from the PC Firefox browser......great

If I re-start the PC whilst the Pi is running, I cannot connect to the Cumulus Dashboard (meanwhile the Pi is still running and sending data to Wunderground).

Why can I not re-connect to (PI-wifi-IP):8998 only after a PC re-boot?

When I setup the Pi I followed the "sticky" and did the

Code: Select all

"sudo crontab -e"

and

Code: Select all

"# Start Cumulus as background task 30s after reboot (delay to allow WiFi to startup)
@reboot (sleep 30;cd /home/pi/CumulusMX;sudo mono CumulusMX.exe) &

# Reboot each day at 0253
53 02 * * * sudo reboot"

But, I read on the thread viewtopic.php?f=27&t=17680&hilit=dashboard

that

I assume you started Cumulus as root using "sudo mono CumulusMX.exe", because the 200 code means "Such a response means the remote resource located at the URL doesn't listen or at least can't respond to a websocket request."., which would happen if Cumulus could not open the listening port because it was started incorrectly.

If I do "sudo mono CumulusMX.exe" at root, I get the response "No such file or directory"

Have I set up something incorrectly here?

You need to do "sudo mono CumulusMX.exe" in the directory in which CumulusMX.exe is located.

You need to do "sudo mono CumulusMX.exe" in the directory in which CumulusMX.exe is located.

freddie, this is the only way that Cumulus will run. If I start it at root I get the message "No such file or directory".

I mentioned the thread viewtopic.php?f=27&t=17680&hilit=dashboard because he also had problems connecting a browser to his dashboard.

I can't start Cumulus in root, Is this why Firefox will not re-connect to the Pi Cumulus dashboard?

[freddie]

You're not being asked to start CUMULUS MX in root - you're being asked to start CumulusMX AS root. Hence the "sudo" part of the command. You should always start it in the location it is installed.

As Freddie said I said start CumulusMX AS root (hence the SUDO command) NOT start it IN Root.

Ahh OK, thanks. Sorry still learning (and a long way to go!).
