when browsing pages i frequently get 'connection refused' messages.
i think it has something to do with the use of a socks proxy because
i don't get these messages when i disable proxy usage.

my socks proxy settings are:
host:       port: 1080

to be more specific: i tested this on the m17 browser component;
i don't know if it has something to do with it, but i noticed that
behaviour on pages with lots of advertising banners.
(e.g.,; on, for example, i get
3-5 'connection refused' messages per page

maybe it's got something to do with the banners being served from a
different domain than the pages themselves...

sorry for being sloppy on the first take,

Reporting comments from dupe bug 49718: Socks proxy causes weird "connection
refused" messages

I was trying to use Mozilla M17 from work on my linux box, it works fine with
our http proxy (though our http proxy is dog slow and only works for parts of
the day), but with socks it says connection refused constantly.  Especially when
submitting forms (but not exclusively, this may be a red herring). 
Unfortunately our socks is the only fast one.  I had this same problem on Win 2k
with Netscape 6.0 PR2.  The same socks proxy works fine with the most recent
Communicator for both Linux and Win 2k.  I cant wait for mozilla to get this
fixed and java support for both linux and windows up to spec, then life will be
really good....  

In the log it would just say error connecting.  Sometimes that would happen even
though it loaded the page.

I'm seeing too this messages, but I do not use any proxy (the proxy is
autoconfigurated at my provider). Not all time, but I also see it using

Now i'll try to find how to reproduse it.

I'd like to look at this problem further, but I need more information:

1- If this is happening to you still, please update this bug and let us know.
2- If you can give us the URL to a page that gets these problems, please add it
3- If we can test with your SOCKS server, please let us know.

This and the linked duplicate are the only report of the problem, so I am
unconvinced this is a broad problem for mozilla users.

I still get this problem.  With the latest build downloaded on the morning of
3-19-2001, I can't get through my firewall to *anywhere* while Communicator
4.76 connecting through the same server reports no errors.  I'm sorry but I
have no control over our internal servers.

Oh, and Mozilla (on Linux) spit out:
Error loading URL 804b000d

changed summary: to reflect that this bug is about partial failures in SOCKS.

qa to me.

There is a timeout problem connecting to a proxy server which is not local. This
has been fixed in 65583, which has a patch ready, but hasn't been checked in yet.
Should be fixed by fix for bug 65583.

VERIFIED: nobody has reported this in a long time. (strangely, our proxy server
is really overloaded (Sparc 20), but did not have this problem...)
Depends on: 65583
