HTTP/1.0 407 Proxy Authentication Required
Proxy traversal failed.
I get that when I try.
It seems like in your network environment there is a HTTP proxy.
Check X-Chat Aqua's proxy settings and perhaps enter your proxy data (you can look it up in your web browser's settings).
If you don't know what I'm talking about, please describe your network environment (that is, from where you try connecting, how you access web pages, etc.), perhaps we can help you further.
So long, Xjs.
I got it.
For some reason a proxy was enabled when I downloaded it, and I just set it to no-proxy.
