Hi ,

I open this topic, as I recently configured an openvidu environment and an external TURN server, then I inserted the following parameter in the Openvidu .env file OPENVIDU\_WEBRTC\_ICE\_SERVERS = ["url = turns: \<your\_turn\_endpoint\>: 443, username = \<your\_username\>, credential = \<your\_credential\> "] obviously customized with my data, but I can’t understand if openvidu connects correctly to this TURN, if it is used or not, how can I verify this?

Best regards

Andrea

In firefox, while openvidu is being used in the browser, you can check it by opening in a new tab: `about:webrtc`

Candidates and Ice Server used appears in a table.
