Certificate issues on old devices (< ~Android 7): Problem adding cities or getting weather data #79

This is because a CA certificate from Let's Encrypt has expired and is no longer updated on old devices.

You need the latest certificate ISRG Root X1 from here. https://letsencrypt.org/certificates/ Download the .pem

For Android it needs to be converted to .crt which e.g. can be done here. http://www.realmb.com/droidCert/ Upload the .pem there and follow instructions.
