Note: Cloud agents are considered 'unreachable' when the Cloud Agent Manager cannot connect to them. There are a few possible reasons
why this may occur:
- Your network contains a firewall that blocks certain hosts or ports. Agent communication occurs over a secure HTTP tunnel
using port 443.
- Your network uses a proxy server that blocks certain Web sites or ports.
- The machine that the Cloud Agent Manager runs on has a firewall that blocks certain hosts or ports.
