Information provided is not enough.
Please provide more info.
does it suddenly stop while working?
any change in the colour or flickering speed of LED?
what does squid log says?
can you ping provide ping isn't blocked etc from Centos box itself
try telnet 80 (telnet on port 80)
configure the logs to debug level. (make sure that you backup the existing syslogd.conf before changing to debug level)
