The software is unable to connect to the internet. If you are otherwise able to browse the internet, there is likely something on your computer which is specifically blocking our software's access. On occasion, overzealous antivirus and firewall software will cause trouble. Please check your antivirus and firewall software to allow access for the Applian software. The domains secure.applian.com and applian.com should be allowed access.
Bitdefender users: After updating our software, Bitdefender might suddenly start preventing access to the internet. We have found that, after receiving the error message, closing and restarting our software will allow access. This process may need to be repeated for each part of our software which accesses the internet (registration, tuning, and guides) and if our software has been updated.
