"Check For Updates" does not work when there is a HTTP proxy

[MiG]

If you use the online update function, it should use the global proxy settings.
atm there is no way using it when sitting behind a proxy.
Perhaps there sould be an option [in the update dialoge or in the global settings] to setup the behavior.

I have attempted to enter proxy settings manually, but still cannot connect to the update server when behind a proxy. The same has been tested successfully when connecting directly to the Internet (no proxy). The configuration wizard is also unable to correct configure the necessary settings when behind a proxy.

Hi,
Until the current FileZilla Client version 3.2.8.1, this bug still exist.
This is the result shown after the update failed:

Status: Disconnected from server
Status: Downloading /updatecheck.php?platform=i586-pc-mingw32msvc&version=3.2.8.1&osversion=5.1
Status: Resolving address of update.filezilla-project.org

Status: Connection attempt failed with "ETIMEDOUT - Connection attempt timed out".
Error: Disconnected from server: ETIMEDOUT - Connection attempt timed out
Error: Disconnected from server

I change the generic proxy settings and still produce the same result.

In my workplace, proxy server applied only to http. I can use ftp directly to internet. So my browser using proxy but my FileZilla client just leave generic proxy settings to none.

I think generic proxy settings is special for ftp proxy in this context.
I pretty sure the update check simply using http get to check for update.
So it seems your generic proxy settings not related to this.
You might need to set another http proxy settings or
just simply use the system proxy settings Eg. IE Internet Options in windows.
if still difficult, just use ftp to download a file that contain the latest version by operating system. If I can use ftp then I can also check for update.

Hope this words might help your team.

The above still does not correct the problem in 3.2.8.1 or in 3.3.0 rc1. Error is as follows:

[[Image(Status: Disconnected from server

If Filezilla would just read the browser settings this would be much easier.

Taken from #8678:

"I would prefer it if the Client used the same protocol to do the downloading than what it uses to do the checking.

i.e.: You're doing the check via HTTPS, so if that works, it should be safe to assume that the download also works via HTTPS.

This isn't the case right now, so while the Client tells me that there's a new update available, it can't download it, as it tries to do the download via HTTP, which requires authentication behind our proxy."

There are two problems:

1) FileZilla does not use global proxy settings.

2) FileZilla checks for a new version using HTTPS, but then tries to download the new version via HTTP.

I just moved over to a new development VM in my work and it's in a domain that uses a proxy server. This issue still exists in the latest version as I can't check for updates any longer. Still fails even though I've entered the proxy server info and credentials in the settings. Info from Help | About below:

Sad but true: That problem still exists with 3.25.1.

I've set both "FTP proxy" and "Generic proxy", and the proxy server is set in the system proxy settings, too.

I can access FTP sites well, but checking for an update fails every time.
