http and https

Hi friends,

I have a local host http://ss3/cgi-bin/page/page_list.cgi running on apache webserver perfectly well. But suddenly, it stopped working and gave an error "Internet explorer Explorer cannot display the webpage". But when i added https, as https://ss3/cgi-bin/page/page_list.cgi the host started working as usual. I had not made any changes. Please help me figure out the options for restoring it to http:// instead of https://. I had also checked the httpd.conf file and everything is normal. Thanks in advance.

Well something changed. What is your operation system and version? Can we see a copy of your httpd.conf?

Did maybe someone change any proxy settings that would affect HTTP transfer, but be transparent for HTTPS?
