sslh-1.22-1 fails to forward http connections. Downgrading to 1.21c-2 solves the issue.

I've got a simple sslh.cfg file like this:

numeric: true;
transparent: false;

listen:
(
{ host: "168.235.104.55"; port: "443"; },
{ host: "168.235.104.55"; port: "80"; }
);

protocols:
(
{ name: "ssh"; host: "127.0.0.1"; port: "22"; },
{ name: "tls"; host: "127.0.0.1"; port: "443"; },
{ name: "http"; host: "127.0.0.1"; port: "80"; }
);

ssh connections get forwarded as expected. But http connections fail like this:

It's fixed upstream by release 1.22.b which landed in Arch shortly after. This report can be closed. Cheers.
