- Under Communication with Secure Access Cloud, one or more rows must have an internally reachable address with only a single FQDN or IP address.
- Internally reachable address fields with multiple FQDNs or IP addresses are not supported by reachability testing.
- Subnets, IP address ranges, and FQDN wildcards are not supported by reachability testing.
- Protocol must include TCP. Reachability testing supports the protocol options TCP - (HTTP/HTTPS) only, Any TCP, and Any TCP, Any UDP.
- Port / Ranges must be configured with one and only one port.
- Under Endpoint Connection Methods, reachability testing only supports Zero-trust connections.
