Connectivity

A node does not connect to the platform

After you've followed the instructions to deploy a node, the node does not show up in the platform.

Here's what you can do:

1. Ensure that your firewall allows outbound 443/TCP traffic.
2. Start the node manually on the command line via tenzir-node and observe the output. In case you see a warning or an error, share it with us.

A node fails to connect with system_error: failed to resolve

You may see this error message when a node attempts to connect to the platform:

platform-client failed to connect: !! system_error: failed to connect: !! system_error: failed to resolve; will retry in 2m

This can happen when additional name servers for custom domains are configured in your /etc/resolv.conf. This is commonly referred to as Split DNS. The name resolution algorithm in our official Linux binaries does not support such a setup natively. A split DNS setup is best implemented by using a local caching nameserver such as dnsmasq or systemd-resolved.
