I have an OpenMV H7 Plus with a standard Wifi Shield.
Has anyone figured out how to send REST requests to a site that uses a “Let’s Encrypt” free certificates? I have an OpenMV H7 Plus with a standard Wifi Shield. When I run the stock “Wifi-Shield/http_client_ssl.py” it connects to host “www.google.com” just fine, but when I change the host to my server (with a Let’s Encrypt certificate) it breaks with an “OSError: [Errno 5] EIO”. I know my site works and has a valid certificate, it gets a “green” certificate badge in chrome…
Am I missing some obvious thing?
