Cloudflare Tunnels without Universal SSL?

Zero Trust Cloudflare Tunnel
1

I’m trying to set up tunnels for a domain, which I did before successfully, but this time I’ve disabled Universal SSL and opted in for using Let’s Encrypt for certificates. I’ve managed to set up the Let’s Encrypt for the whole domain via DNS challenges and the domains do work but I’m having trouble with the Tunnels.

I get the “ERR_SSL_VERSION_OR_CIPHER_MISMATCH” error when accessing the public hostname.
When I disable the proxy for the tunnel it throws the “ERR_ADDRESS_UNREACHABLE” error

HTTP does work.
SSL mode is set to Full (Strict)

When running curl -L -k -v it throws the following error:

curl: (35) error:0A000410:SSL routines::sslv3 alert handshake failure

Any idea if I can make the tunnels work on HTTPS with Let’s Encrypt and without Universal SSL?

You need an Edge Certificate of some kind, whether that’s Universal, Advanced, or Custom.

You cannot pass through the certificate from origin even if you use Tunnel, there has to be one on the edge as well.
