When checking your relays in the Admin UI, you may see a node status of isolated. The isolated status indicates that the relay cannot dial or successfully handshake an authentication with any gateways. Isolated relays may successfully health check resources, but the relays will be unavailable for use for user connections because there is no way for the user to hop from a gateway to an isolated relay.
How to resolve this issue and get your relay to an online status
Ensure that network routing and firewall settings allow the relay to connect to one or more gateways. Once this is resolved, the status will change from isolated to online.
