Webflow SSL error when partial hosted behing NGINX

Hey, we’re hosting our webflow site behind nginx to also allow our blog to be hosted under the same domain via SEO, and used a few nginx conf snippets from this forum to support it. For some reason, this morning we’ve noticed the site go down due to some opaque SSL errors, like:

SSL_do_handshake() failed (SSL: error:14094438:SSL routines:ssl3_read_bytes:tlsv1 alert internal error:SSL alert number 80) while SSL handshaking to upstream

I’m guessing there was a change to the supported SSL versions for your domain, what do we need to do to configure the ssl proxy to make this work?
