I'm running Cumulus MX 3.0.0 b3043 on a Pi Zero. Sometimes when I connect to Cumulus from my laptop with http://192.168.1.94:8998/index.html the page never loads. Sometimes I get a small box with Connection closed, sometimes nothing at all just the spinny wheel. If I leave the page trying to connect it sometimes does after 30 - 60 minutes. Other times it connects first time.
I've tried Firefox 68.0.1 and IE 11.239. I can still PuTTY into the pi from the laptop. Router is the same one I've always had and the Pi has not been upgraded since it was built .
[Edit] Forgot to mention that the Pi is connected via wireless as is the laptop.
Any suggestions as to where to start with sorting this problem?
Many thanks,
Dave

Re: Connection closed error
Not sure, but my personal guess is it would depend on the processor load on the Pi Zero. It is a very low powered Pi so if you try to make a browser connection when the processor is heavily loaded the connection will either take a long time or time out. And vice versa if it is lightly loaded it will connect right away.

Re: Connection closed error
Hi David, thanks for your response.
The Pi Zero is used for Cumulus only. "top" shows the load average is around 0.15 to 0.2. CPU is running at 10%.
I'm not familiar with Linux but doing a few searches pointed me to netstat. Looks like port 8998 is open on the Pi
Are there any log files I can look at which might help?
I'll reboot the Pi and the router and report back.
Thanks, Dave

Re: Connection closed error
MXdiags folder has the logs. Having Debug and Data logging ticked may be helpful.Are there any log files I can look at which might help?
Updating to latest MX version would also be a recommendation.
Enjoy,

Re: Connection closed error
Thanks Paul.
I thought I'd go the whole hog and update to Buster. I've read that there is a bit of a problem with getting the correct version of Mono to work with Cumulus.
What are your recommendations?

Re: Connection closed error
Sorry, I've only used CumulusMX with Windows and can't suggest anything for other systems.
Enjoy,

Re: Connection closed error
No problem. I've followed the install instructions by ExperiMentor viewtopic.php?f=27&t=16931 and I seem to have a working system. What files do I need to copy over from my old system? I've done /data /web /webfiles /interface and Cumulus.ini
Thanks,
Dave

Re: Connection closed error
Mark, who is maintaining CumulusMX, has been adding the list of files updated at each build update so you would need to check each update post from b.3043 to current. However, I usually install the full new download and copy in the most current \data folder, Cumulus.ini, and any \web files that I may have edited.
Enjoy,
Paul

Re: Connection closed error
Hi Paul, I have CumulusMX 3050 working without the "Connection closed" error and with all my old data! It is running Raspbian Buster on a Pi 3 B+. Next to try a Pi zero W as I need the Pi3 for something else. I'll report back.
Thanks for your support,
Dave
