Proxy settings not working

Don't you have any details to add? Like, for example, the description of the proxy you are trying to use, or which error message you got?

I can't do magic from such a short, vague sentence.

It is so simple as described. It doesn't work at all.

To register a twitter account, it doesn't detect proxy settings. Neither http_proxy or https_proxy enviroment variables. After register, it isn't stable to use proxy setup. From times to times it ignores the proxy setup and try to use direct connection (verified via tcpdump). It mostly get lost after return from a pm-suspend.

After you 'quit' and restart polly, it comes up with "localhost:8080" as proxy setup.

Maybe one important information missing is regarding the window manager: KDE and 4.10 over an Ubuntu LTS (12.04).

Polly at version 0.93.9-0~precise1.

What exactly did you set on Edit->Preferences->Proxy?

Can you check in gconf-editor whether the proxy settings are kept when you quit and restart?

Using gconf-editor, I can see proxy settings aren't commit accordingly.

And it remains not working. It loads timeline once and... that's all. It hangs.

Starting polly from console, I can se the following:

What happens when you set the parameters directly in gconf-editor?

(quit and restar Polly to be sure)

It keeps the proxy information, access the timeline once and... hangs with an output like the one in my previous comment.

I attempted using corporate VPN.

So I started session with proxy flag enabled. And polly didn't connect directly. Once I disable the checkbox, timeline updated accordingly.

Once I started VPN and enabled proxy, it failed again, with the same previous error:

I set up a local squid proxy and couldn't reproduce this bug.

Any particularities of the proxy you are using?

As far as I can see it is a bluecoat proxy:

http://www.bluecoat.com/

Connecting on it:

telnet www-proxy.company.com 8080
Trying 1.2.3.4...
Connected to www-proxy.company.com
Escape character is '^]'.
HEAD / HTTP/1.0

HTTP/1.1 400 Bad Request
Cache-Control: no-cache
Pragma: no-cache
Content-Type: text/html; charset=utf-8
Proxy-Connection: close
Connection: close
Content-Length: 1442

Connection closed by foreign host.

I can't tell further than this since it is a corporate proxy. But, except Polly, everything else works just fine.

Does this proxy use authentication?

Nops. Only proxy.

env http_proxy="http://www-proxy.company.com:8080" https_proxy="http://www-proxy.company.com:8080" lynx -dump http://twitter.com | head -10
   #[1]Twitter

I'm stuck, then. I can't figure out a way to reproduce this.

The issue might be on SocksiPy rather than on Polly, but I'm not sure.

Is there a way to enable debug?

Not as far as I know. I have no control over the proxy part, it's a third-party library.
