[Freeswitch-users] Using TLS certificate with intermediate CA

Hello everyone, I am currently struggling to get FreeSWITCH (1.10.5-release-17-25569c1631~64bit) to send the intermediate CA certificate for a Let's Encrypt X.509 certificate to be used for protecting SIPS traffic. I included the certificate chain in agent.pem: -- 8< -- -----BEGIN EC PARAMETERS----- *REDACTED* -----END EC PARAMETERS----- -----BEGIN EC PRIVATE KEY----- *REDACTED* -----END EC PRIVATE KEY----- -----BEGIN CERTIFICATE----- *SERVER CERT* -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- *INTERMEDIATE CERT* -----END CERTIFICATE----- -- 8< -- Still, clients are complaining about an invalid CA and openssl s_client hints at only the server cert being sent in the server hello. What did I miss? Thanks, Thilo
