STUN Discovery Unavailable

Hi, I have deployed a set of connectors on AWS . In the admin console, they are connected but in their status details, I see “STUN Discovery Unavailable”.

  1. Does that mean my client wont use peer-to-peer with these connectors?
  2. What is the requirement or what did I miss to make this STUN discoverable?


I just figured out my outbound UDP security group was not set correctly. I’ve updated the UDP rule to allow UDP 0 - 65535.

Glad to hear you got it figured out!

For anyone who stumbles across this in the future - the STUN Discovery Unavailable will indeed suggest that p2p tunnels will not be establishable with this connector, and the culprit is almost always blocked outgoing UDP ports.
