Organizations often block a number of network ports.

Ask the administrator to allow

  1. TCP ports 7000, 8008, 8009, 47000, 7100, 49228, 50259
  2. UDP ports 62572 and 54780
  3. If using Google Cast, UDP port 1900
  4. If using Windows computer or a Mac computer, UDP port 5353.


  • The display’s casting ID may not have propagated yet through the network or may be cached on the network when it’s not actually available. Wait several minutes and attempt to connect again.
  • The network must be configured to run Bonjour and mDNS, and Multicast must be enabled.
  • Ensure your device and display are on the same VLAN or subnet.
