I am connecting to my corporate vpn using openconnect and network-manager-openconnect. When I connected to the vpn, I tried navigating to localhost to hit my local web server where I was doing some development.

The page could not load and I could see Connecting 192.168.233.38 (or some similar address) in the Firefox window. If I use http://127.0.0.1 this works fine.

Using ping localhost from a console works fine and shows localhost as 127.0.0.1.

Very frustrating! Any ideas?

I guess openconnect configures http proxy to be used by FF. ('Connection through HTTP proxy, including libproxy support for automatic proxy configuration.') FF Preferences - Advanced - Network etc, you should exclude localhost.

Another option is a change of resolv.conf that will redirect even localhost. cat it.

I'd try wget -vvv and see exact step which is wrong.

When I initially started firefox, it was set to use the system proxy. According to this unix stackexchange answer:

The system proxy settings should be stored as system-wide variables, present in /etc/environment

In my case I set them in .pam_environment instead of /etc/environment. However, I set only http_proxy and https_proxy but not no_proxy so the proxy was being used everywhere.

I was able to resolve the problem by:

  1. Modifying .pam_environment with the proxy server related environment variables, setting no_proxy for localhost, etc. and logging out and then back in.
  2. Resetting Firefox according to the help.
