Network diagnostics tests DNS resolution, port accessibility, routing paths, and firewall rules to identify connectivity problems. Run checks against your target host to pinpoint whether the issue is DNS, routing, firewall, or port-related, then follow recommended next steps for resolution.

Yes. Network diagnostics performs end-to-end checks including ping, DNS resolution, and port accessibility tests to isolate whether connection refused or timeout errors stem from DNS failure, unreachable routes, closed ports, or firewall blocking.

Network diagnostics tests port accessibility by attempting TCP connections to specified ports on target hosts, analyzes firewall rules affecting those ports, and reports which ports are reachable or blocked to help identify access barriers.

Network diagnostics analyzes routing paths and performs traceroute checks to map the network route to your target. This reveals where packets are dropped or delayed, helping identify whether intermittent issues stem from routing problems or intermediate network nodes.

Network diagnostics analyzes firewall settings and their impact on connectivity to target hosts. It reports which firewall rules block or allow traffic, helping you determine whether firewall configuration is preventing access to required ports or services.

Yes. Network diagnostics applies the same end-to-end diagnostic workflow—DNS, port, route, and firewall checks—to both client access and server-to-server connectivity scenarios to quickly identify outage root causes and recommend next steps.
