App Control: API is not reachable errors on console

App Control: API is not reachable errors on console


  • App Control:  7.x and 8.x
  • App Control on DMZ
  • Red Dot and 'API is not reachable' on Administration > System Configuration > Advanced Options > API Access Enabled


  • 'API is unavailable. This page will not be functional' errors when loading console pages
  • 'You are not authorized to view this page' errors when loading console pages
  • Blank User Roles when trying to Edit or Create a new User
  • Unable to Globally Approve files
  • Unable to view Software Rules page
  • 'API Error from page....returned http code 404' error in PHP_Errors.log


  • These errors are a result of the API not being able to communicate with the server, due to the server being on a DMZ and not being able to reach out to the DNS server for host name resolution.


  1. Add the following entry to your Host File, located at C:\Windows\System32\Drivers\ETC: <FQDN>
  2. Run the following command to flush the DNS records, allowing the host file change to take place:
    ipconfig /flushdns
  3. Log out and back in to the console.

Additional Notes

  • The 'Server Address' listed in the Console -> Gear dropdown -> System Configuration -> General tab needs to match the <FQDN> being added to the host file
