So, it seems it's not true that squid is using http/1.0, but the guy on
the other side told me so. According to the log, do you think I can
somehow make it working or is it definitely problem on the samba.org
webserver?
That ERR_PROTOCOL_UNKNOWN indicates that your proxy is trying to
SSL-Bump the CONNECT tunnel and not understanding the protocol inside
the TLS layer - which is expected if that protocol is HTTP/2.
For now you should be able to use
<http://www.squid-cache.org/Doc/config/on_unsupported_protocol/> to
allow these tunnels. Alternatively use the "splice" action to explicitly
bypass the SSL-Bump process.
