Hello, I'm succesfuly using Openconnect 6 or 7 in different configurations, but I have a problem with just one proxy with basic auth. I'm able to connect through it with different programs (wget, corkscrew, openvpn...), but when I run this command, no joy. # openconnect SERVER --proxy=http://USER:PASSWD at PROXY:8080/ --proxy-auth Basic POST https:/SERVER/ Attempting to connect to proxy PROXY:8080 Requesting HTTP proxy connection to SERVER:443 Got HTTP response: HTTP/1.1 407 Proxy Authentication Required Server: Sun-Java-System-Web-Proxy-Server/4.0 Date: Fri, 28 Nov 2014 11:07:04 GMT Content-length: 146 Content-type: text/html Proxy-authenticate: Basic realm="PROXY" Connection: close Set-Cookie: BIGipServerpool_proxy=****o8080; path=/ HTTP body length: (146) Attempting HTTP Basic authentication to proxy Error fetching HTTPS response Failed to open HTTPS connection to SERVER I suspect the proxy doesn't respond immediately after request, can it cause this kind of behaviour? Thanks for reply, Panther
