Hi I have a verto client trying to connect to FS using Chrome V87 but we have DTLS problems. The openssl version we are using on FS side is OpenSSL 1.0.2k-fips FreeSWITCH (Version 1.8.4 64bit) FS LOG - Chrome V87 FAILED CONNECTION 2020-12-03 11:23:06.762291 [ERR] switch_rtp.c:3199 video Handshake failure 1 2020-12-03 11:23:06.762291 [INFO] switch_rtp.c:3200 Changing video DTLS state from HANDSHAKE to FAIL 2020-12-03 11:23:06.832295 [ERR] switch_rtp.c:3199 audio Handshake failure 1 2020-12-03 11:23:06.832295 [INFO] switch_rtp.c:3200 Changing audio DTLS state from HANDSHAKE to FAIL 2020-12-03 11:23:06.852295 [NOTICE] switch_rtp.c:3181 Hangup verto.rtc/3520 [CS_EXECUTE] [DESTINATION_OUT_OF_ORDER] 2020-12-03 11:23:06.852295 [DEBUG] switch_core_media.c:7470 verto.rtc/3520 Video thread ended 2020-12-03 11:23:06.872305 [INFO] conference_loop.c:1670 Channel leaving conference, cause: DESTINATION_OUT_OF_ORDER 2020-12-03 11:23:06.872305 [DEBUG] switch_core_session.c:2639 verto.rtc/3520 skip receive message [DISPLAY] (channel is hungup already) 2020-12-03 11:23:06.872305 [DEBUG] mod_conference.c:2467 verto.rtc/3520 skip receive message [TRANSFER] (channel is hungup already) 2020-12-03 11:23:06.872305 [DEBUG] switch_core_media.c:12220 verto.rtc/3520 skip receive message [BITRATE_REQ] (channel is hungup already) 2020-12-03 11:23:06.872305 [DEBUG] switch_core_codec.c:248 verto.rtc/3520 Restore previous codec opus:116. 2020-12-03 11:23:06.872305 [DEBUG] switch_core_session.c:2886 verto.rtc/3520 skip receive message [PHONE_EVENT] (channel is hungup already) 2020-12-03 11:23:06.872305 [DEBUG] switch_core_state_machine.c:650 (verto.rtc/3520) State EXECUTE going to sleep 2020-12-03 11:23:06.872305 [DEBUG] switch_core_state_machine.c:584 (verto.rtc/3520) Running State Change CS_HANGUP (Cur 1 Tot 3) 2020-12-03 11:23:06.872305 [DEBUG] switch_core_state_machine.c:847 (verto.rtc/3520) Callstate Change ACTIVE -> HANGUP 2020-12-03 11:23:06.872305 [DEBUG] switch_core_state_machine.c:849 (verto.rtc/3520) State HANGUP 2020-12-03 11:23:06.872305 [DEBUG] switch_core_state_machine.c:60 verto.rtc/3520 Standard HANGUP, cause: DESTINATION_OUT_OF_ORDER 2020-12-03 11:23:06.872305 [DEBUG] switch_core_state_machine.c:849 (verto.rtc/3520) State HANGUP going to sleep The weird thing is the connection works ok when the version of chrome is V86.
