Version: (using KDE 4.3.1) Installed from: Debian testing/unstable Packages It seems that the http proxy settings are not used. According to netstat, the kopete process tries to connect (SYN_SENT) directly to some host on the https (443) port. Because of this, I can not log in at all (port 443 is filtered). Konqueror does use the proxy settings and works well with https, so the settings are OK.
