I ran into this yesterday with a CouchDB running on an Ubuntu 16.04.7 LTS Droplet. I don't think this is an issue with the droplets though and updating to the latest release did not solve the problem. In my case I could not connect to the CouchDB using the Chrome and Opera web browsers running on my Late `09 Mac Mini. I get an "SSL certificate has expired" alert for both the website and the CouchDB running on that server. Firefox, however, works fine with that Cert. So I tested it on a new Raspberry Pi with both the Chrome and Firefox browsers and got the same result. Works in Firefox and not in Chrome. I also tested it on my old iPhone 5s and Safari did not work but Firefox does. I think this is related to what's described here just a couple days ago: "Let’s Encrypt’s root certificate has expired, and it might break your devices" https://techcrunch.com/2021/09/21/lets-encrypt-root-expiry/ https://techcrunch.com/2021/09/21/lets-encrypt-root-expiry/
