Dedicated devices are often behind corporate firewalls, preventing Esper's backend from communicating with them (or vice-versa). Please make sure to allow the following URLs and Ports if your fleet runs behind such a firewall.
Esper also offers streamer services and static IPs. Need these services? Get in touch.
