ERR_SSL_PROTOCOL_ERROR with nginx proxy

I am using fly to deploy an global nginx proxy as described in the app guides

I am able to access my fly app over https.
However, when i try to access another domain, which is a CNAME of my fly application, I am getting a handshake error

Please help

If you haven’t already, you’ll need to use flyctl certs add <domain> to let us know we should generated a certificate. Since you’ve already done a CNAME, that should just work within a minute or two.

If you’ve already added the cert with flyctl, and you’re getting that error, there’s something else wrong. The first thing to check is to make sure the CNAME shows everywhere.

I can have a look if you let me know what the domain you’re using is.

Thanks for the assist kurt. Turns out i missed the addcert part. Things are working now.

Ahhh good news! We should make that step more obvious, I think.
