I'm trying to set up a stunnel for WebDav on Windows. I want to connect 80 port on my local interface to 443 on another machine in my network. I can ping the machine remote machine. However when I use the tunnel, I'm getting this error all the time

SSL state (accept): before/accept initialization
SSL_accept: 140760FC: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

There is nothing in the logs on the other machine and here's my stunnel connection config

[https]
accept  = 127.0.0.2:80
connect = 10.0.0.60:443
verify = 0

I've set it up to accept all certificates so this shouldn't be a problem with a self-signed certificate remote host uses.

Does anyone knows what might be the problem that this connection cannot be eastablished?
