Using https://www.sslshopper.com/ssl-checker.html#hostname=https://api.amplitude.com/ has the details and its indeed the COMODO certificate that has expired.

It is unknown how good/actual sslshopper is.

Check my SSL Certificate | Is your SSL certificate valid and installed ? says there are no issues
Check SSL Certificate - GeoCerts says all good
etc
