Scheduled Task Check for Coldfusion Updates gets 403 error

I am running Coldfusion10 on RedHat Linux6. Coldfusion Administration Scheduled Task runs a check for Coldfusion updates every 30days. This month the access_log had the following entry.

xxx.xxx.xxx.xxx - - [16/Feb/2016:12:32:15 -0600] "GET /CFIDE/administrator/updates/task/checkupdates.cfm HTTP/1.1" 403 316 "-" "CFSCHEDULE"

If I run it manually from the Scheduled Task, I see "This scheduled task was completed successfully" message but still see the error in the log.

There is nothing in the application.log

When I click the Updates under Server Update, the hour glass spins for a long time, and it times out with the following error.

Could someone tell me what is wrong?

Thank you,
