Troubleshooting Agent Connectivity

Problem: My network contains security policies that prevent agents from reaching the SeaLights platform

This is normally caused due to security policies related to Firewalls, or other networking-related security configurations that prevent access to the SeaLights API. To verify this is the case, try running a cURL command to your dashboard URL:

curl -vI https://<YourCustomDNSName>.sealights.co

HTTP/2 200 code should be returned. If this code is received, you can access the SeaLights API and there is no need for this document.

If using a proxy, you should add the relevant parameter

curl -vI https://<YourCustomDNSName>.sealights.co --proxy http://myproxy.mycompany.int

If you need a generic Sealights endpoint, you can use https://connect.sealights.co in your command.

In case this command fails, it is important to understand why. Looking at the detailed output (given by the -vI flags) can point us in the right direction.

The above cURL commands run on native Linux.

• If using Windows, you will need to run it from a PowerShell prompt as it allows curl commands as an alias to the native Invoke-WebRequest cmdlet that you can use as well. For example, Invoke-WebRequest -Uri https://<YourCustomDNSName>.sealights.co -UseBasicParsing | Select-Object StatusCode,StatusDescription If a proxy is required, you can add -Proxy <Uri> parameter to the first part of the command. More details can be found in Microsoft’s Official documentation page.

• If running on a Linux container without cURL, you can install it using apt-get update && apt-get install -y curl or use the wget equivalent. For example, wget --server-response --spider https://<YourCustomDNSName>.sealights.co . If a proxy is required, you can add -e use_proxy=yes -e http_proxy=<proxy_url> parameters to your command.

Solution

If a firewall is present, it needs to allow network traffic to reach the SeaLights platform, and depending on your organization’s policy, you can use one of the following solutions.

Allow outbound traffic to Sealights' domain

The Firewall should allow outbound connections on port 443 (TLS v1.2) to our domain https://*.sealights.co. For a more restrictive rule, you can open the connections to your Sealights dashboard URL only.

Allow outbound traffic to Sealights' range of IP addresses

Sealights integrates with F5 Volterra. To ensure proper connectivity, configure your firewall or access control rules to allow traffic to and from the IP address 159.60.128.87, which serves as the central ingress point for all Sealights servers.
