If you can build Freeswitch, change the code in switch_rtp.c as below, #if OPENSSL_VERSION_NUMBER >= 0x10100000 dtls->ssl_ctx = SSL_CTX_new((type & DTLS_TYPE_SERVER) ? DTLS_server_method() : DTLS_client_method()); #else - dtls->ssl_ctx = SSL_CTX_new((type & DTLS_TYPE_SERVER) ? DTLSv1_server_method() : DTLSv1_client_method()); + switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(rtp_session->session), SWITCH_LOG_INFO, + "Negotiated DTLS1.2 between remote-host:%s, local-host:%s\n", rtp_session->remote_host_str, rtp_session->local_host_str); + dtls->ssl_ctx = SSL_CTX_new((type & DTLS_TYPE_SERVER) ? DTLSv1_2_server_method() : DTLSv1_2_client_method()); #endif /Kaiduan On Fri, Dec 4, 2020 at 1:09 PM Jazmin Marina Florez Marino < Jazmin.Marino@on24.com> wrote:
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

The weird thing is the connection works ok when the version of chrome is V86. Some weeks ago chrome was updated and we detected this issue.
