    We have 6 rtsp streams set up. The threads work fine, but they fell off with a message today:

    17:33:05,779 ERROR bstractDTLSTransport - Stun-Clbk-thread udp// Close socket after 10 tries
    17:33:05,779 INFO Session - Stun-Clbk-thread udp// Failed to create dtls client protocol, mediaSession 670b91e0-2fe1-11ea-afb6-970dd0705161
    17:33:05,779 INFO MediaSession - Stun-Clbk-thread udp// Stop MediaSession id: 670b91e0-2fe1-11ea-afb6-970dd0705161

    Can you tell us what that means?
    Streams have recovered from rebooting the webcallserver.

    Good day.
    This means DTLS connection error. DTLS connection is established to play WebRTC stream, DTLS 1.2 is used by default. Please update WCS to latest build from this page, then set DTLS error logging as described here.
    After that, you could add User-Agent string from dtls-error.log to /usr/local/FlashphonerWebCallServer/conf/dtls0_ua file, this enables DTLS 1.0 usage for this User-Agent.
    Please check this topic for answer. Please note you should not duplicate the same question in several topics.
