[SR-Users] Websocket TLS Issue

Hi Guys, I am trying to setup the following flow: Browser >> WSS >> HA Proxy >>> WSS >> Kamailio But getting TLS errors in Kamailio logs: *[29634]: ERROR: <core> [tcp_read.c:1321]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7f68ebe872b0 r: 0x7f68ebe87330* *[29631]: ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number* Browser <-----wss---->Kamailio works fine with same certs. Both HA Proxy and Kamilio are installed on separate servers, hosting on same port with different domain. Kamailio tls.conf has method = TLSv1 *@HA Proxy:* openssl s_client -connect HA-PROXY-DOMAIN:*10443* SSL-Session: Protocol : TLSv1.2 *@Kamailio :* openssl s_client -connect KAMAILIO-DOMAIN:*10443* SSL-Session: Protocol : TLSv1 So I made HA Proxy to be on TLSv1 "ssl-default-bind-options force-tlsv10" But still I get the same TLS error in Kamailio. *HA Proxy config looks like:* *frontend public* * bind *:10443 ssl crt /etc/haproxy/certs/cert.pem* * acl is_websocket hdr_end(host) -i m1.some-domain.com <http://m1.some-domain.com>* * use_backend wss if is_websocket* * default_backend wss* *backend wss* * timeout server 600s* * server ws1 k1.some-domain.com:10443 <http://k1.some-domain.com:10443>* * server ws1 k2.some-domain.com:10443 <http://k2.some-domain.com:10443>* Need some direction, thanks in advance.
