Hello,

please format your e-mail only with black – its really hard to read (it might be related to my client, though).

Have you already checked the file system access rights to the certs if kamailio can actually read them?

Cheers,

Henning

certificate = /etc/certs/webrtc.killermobile.mobi/cert.pem

ca_list = /etc/certs/demoCA/cert.pem

[client:default]

verify_certificate = yes

require_certificate = yes

and tried:

[server:default]

and error log:

Then, i try with TLSv1+

[server:default]

method = TLSv1+

verify_certificate = yes

require_certificate = yes

private_key = /etc/certs/webrtc.killermobile.mobi/key.pem

certificate = /etc/certs/webrtc.killermobile.mobi/cert.pem

ca_list = /etc/certs/demoCA/cert.pem

[client:default]

verify_certificate = no

require_certificate = no

and log is:

Jul 15 03:08:33 ip-172-31-44-170 sbin/kamailio[17826]: ERROR: tls [tls_server.c:1283]: tls_h_read_f(): protocol level error
