[SR-Users] Errors with TLS

Hi everyone, All my environment was working properly. But a few days ago I've started to have problems with my websocket connectios. Everytime I try to register my websocket Kamailio log this Dec 20 09:02:10 prod-kamailio /usr/sbin/kamailio[599]: ERROR: tls [tls_server.c:1330]: tls_h_read_f(): protocol level error Dec 20 09:02:10 prod-kamailio /usr/sbin/kamailio[599]: ERROR: tls [tls_util.h:50]: tls_err_ret(): TLS accept:error:0A000416:SSL routines::sslv3 alert certificate unknown (sni: unknown) Dec 20 09:02:10 prod-kamailio /usr/sbin/kamailio[599]: ERROR: tls [tls_server.c:1334]: tls_h_read_f(): src addr: IP_webclient:61423 Dec 20 09:02:10 prod-kamailio /usr/sbin/kamailio[599]: ERROR: tls [tls_server.c:1337]: tls_h_read_f(): dst addr: IP_Kamailio:8443 Dec 20 09:02:10 prod-kamailio /usr/sbin/kamailio[599]: ERROR: <core> [core/tcp_read.c:1476]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7fbc423053b0 r: 0x7fbc423054d8 (-1) My tls.cfg: [server:default] method = TLSv1.2+ verify_certificate = no require_certificate = yes private_key = /etc/kamailio/cert/clave_SSL.key certificate = /etc/kamailio/cert/certificado.pem Kamailio version: root@prod-kamailio:/etc/kamailio# kamailio -v version: kamailio 5.6.3 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 12.2.0 I don't know why it stopped working.
