# Diagnostic tools

*Applies to: Pearl-2, Pearl Mini, Pearl Nexus, Pearl Nano*

Diagnostic tools are available to help you troubleshoot your device's setup and network connection. You can run them using the Admin panel.

Available diagnostic tools:
- **Connectivity status**: Display the status of critical network connections
- **Ping**: Test if the device can reach a specified destination server on the network. Not all networks support ping.
- **Trace route**: Trace the route that packet traffic takes to get from the device to a specified destination server on the network. Not all networks support traceroute.
- **Bandwidth test**: Display the available upload and download bandwidth speed in Mbps.
- **Domain name resolution**: Confirm that the domain name of the DNS server configured on the device is resolvable.
- **Probe**: Check if a network port is open on the network side.

Using the Admin panel, diagnostic tools are accessed from the Configuration menu when you select **Network** then the Network Diagnostic Tab.

The following table describes what the colored icons in the results indicate.

**Diagnostic test result icons**

| **Icon** | **Description** |
| --- | --- |
| Green Checkmark | The diagnostic test result is okay. This can also mean that a specific feature is enabled on the device. |
| Grey X | The feature or option is disabled on the device. |
| Red X | The diagnostic test result is not okay. An error was detected. |

### Connectivity status results

The following table describes the Connectivity status diagnostics results shown on the Admin panel (and, where applicable, the device's own screen).

| **Diagnostic** | **Description** |
| --- | --- |
| DNS | Check if the device can resolve host names with their associated IP address using the DNS server that is configured for it. |
| Captive portal | Check for connectivity issues caused by a Captive portal. An **okay** result can indicate several conditions: no captive portal is detected and the device can successfully reach the Internet, or a captive portal is detected and the device can successfully reach the public Internet. |
| Internet | Check if the device is connected to the Internet by sending a ping to IP address 8.8.8.8 on the Internet. |
| HTTP (port 80) | Check if traffic can be sent and received over the network using HTTP port 80. |
| HTTPS (port 443) | Check if traffic can be sent and received over the network using HTTPS port 443. |
| Support server | Check if the connection to the Epiphan support server is enabled and, if enabled, confirm that the device can establish communication with the server. A successful connection is required to use the Epiphan Edge remote login feature. |
| Epiphan Edge™ | Check if the Epiphan Edge remote management feature is disabled on the device and if it can successfully connect to Epiphan Edge. |
| Public IP | Display the public IP address of the device. Knowing the public IP address is useful when configuring SRT, especially if the device is behind a NAT on the network. An empty result means the IP address was not reported. |
| mDNS | Shows the device hostname |

From the interfaces tab on the network page of the Admin panel, additional networking information is displayed: MAC address, IP address, Network mask, Default gateway, DNS servers, Hostname.

If after performing a connectivity test errors are seen for Epiphan Edge and/or Support server while Internet, Port 80/443, and DNS pass, you may need to whitelist certain Epiphan server FQDNs in your firewall settings. For the list of Epiphan server FQDNs, see "Fully Qualified Domain Name (FQDN) considerations."

**Device differences**
- **Pearl-2, Pearl Mini:** Diagnostic tools can also be run from the touch screen (tap **Settings > Network**, select **Connectivity Status**; more tools are on the second page under **Network Tools**).
- **Pearl Nano:** Diagnostic tools can also be run from the front screen (not a touch screen) using the same **Settings > Network > Connectivity Status** path; more tools are on the second page under **Network Tools**.
- **Pearl Nexus:** No device screen exists (headless) — diagnostic tools are only available from the Admin panel.
