You give no useful information in your post.

What is the proxy? Did you configure it yourself? Does the site work when you DON'T use a proxy. What distro of Linux are you using?

Try giving people something usable rather than such a vague request.

When I log to the website the web proxy server has detected a problem while it able to access other websites. Yes the site work when no proxy. I am using red hat linux.
I tried to allow the site in the access control list but its not working the same problem occur. Is there other method to solve my problem.
