Cumulus Support

Hello,

Thank you in advance for your assistance.

I have been running CumulusMX and uploading to Windy.com successfully for many months and just recently this has 'broken, when viewing on windy.com the statement "Error loading or rendering station data" is displayed. I have checked my settings and confirmed that they are correct and that the API is correct but no joy. Are there are logs that I can look at to investigate further.

I asked on the windy community forum, hoping they may be able to assist but they suggested I ask here.

I am running the latest Cumulus MX 3.13.8 b3154

Thanks

Andrew

Hi there

We have had this issue before and it was solved for me and others in this topic.

viewtopic.php?f=40&t=19771

It seems that Windy.com changed the use of security certificates and Raspberry Pi did not.

I hope this works for you.

Hi @AndyKF650

Great, I'll check that thread out.

Cheers

Andrew

When I looked at the logs, it says...

2021-11-29 17:40:00.521 Windy: ERROR - The SSL connection could not be established, see inner exception.

Is that the same issue as described in the thread?

Hi Andrew

Yes it is the same issue.

You need to run the following code on your RPi in a terminal session to update the " mozilla/DST_Root_CA_X3.crt " certificate:-

sudo nano /etc/ca-certificates.conf

Put a ! in front of the line: /mozilla/DST_Root_CA_X3.crt
Save the file: Ctrl-X, y

Then update the certificates with:-

sudo update-ca-certificates

Then reboot your RPi, the Windy.com upload will restart and you should see your data within an hour or so.

Hi Andy,

I realised what I have been doing wrong now!

I thought I was updating the certificates but I wasn't doing it correctly and your step by step post has made me realise - D'oh! Thanks very much for taking the time to help me.

The logs are now showing
