World Air Quality Index - SSL: CERTIFICATE_VERIFY_FAILED

Configuration
1

Recently I have enabled the World Air Quality Index component and have noticed many errors/warnings in the log file. The error indicates that it can’t verify a SSL certificate (Not sure which).

An extract of my log:

Has anyone else seen this or experienced this issue? It seems the data is retrieved, however should be good if this issue could be resolved.

Yup, their SSL certificate on https://waqi.info has expired. I’ve contacted them already about this.

Ha! Why I didn’t think of that myself :blush: They are using LetsEncrypt so better they create a script to update their certificate (as by default LetsEncrypt SSL certificates are only valid for 90 days).

Contacted them myself as well and received a confirmation email today that the SSL certification was renewed :slight_smile: They explained that for some reason they haven’t received a renewal notification.
