Resolution

1. Make sure the proxy settings are properly set in the VAMI page.
2. Make sure that the settings are proper by checking the proxy file under /etc/sysconfig
3. Validate the settings as per KB 316490
4. If you are still getting the same error, edit the file /etc/wgetrc and update the following details with the proxy settings. Remove the leading # from https_proxy, http_proxy, and use_proxy.

[BEFORE]
# You can set the default proxies for Wget to use for http, https, and ftp.
# They will override the value in the environment.
#https_proxy = http://proxy.example.com:18023/
#http_proxy = http://proxy.example.com:18023/
#ftp_proxy = http://proxy.example.com:18023/

# If you do not want to use proxy at all, set this to off.
#use_proxy = on

[AFTER]
# You can set the default proxies for Wget to use for http, https, and ftp.
# They will override the value in the environment.
https_proxy = http://proxy.example.com:18023/
http_proxy = http://proxy.example.com:18023/
#ftp_proxy = http://proxy.example.com:18023/

# If you do not want to use proxy at all, set this to off.
use_proxy = on
