Error when trying to set up an SSL/TLS configuration
I'm trying to configure an SSL/TSL configuration in our test environment so we can send ADT messages to an external server. I've verified connectivity/firewall to the external server.
type is set to Client, Server certificate verification is set to Require.
I have received a certificate from the external supplier and linked that in the "File containing trusted Certificate Authjority certificate" field. (I've also imported it into the cert store and tried using %OSCertificateStore).
My client certificate is in PEM format, the decrypted key was extracted using SSLOpen. Protocol enabled is TLSv1.2 (I've tried with the others as well.)
When running a test I get this error:- ERROR #988: SSL connection failed. SSL/TLS error in SSL_connect(), SSL_ERROR_SSL: protocol error, error:14094416:SSL routines:ssl3_read_bytes:sslv3 alert certificate unknown
Is anyone able to assist in deciphering this error, or helping me sort the configuration out?
Many thanks
Do you have CA cert for the CA used to sign external server's cert?
You need that and not external server's cert itself.

Thanks for the advice, I will check that. I think I have the certificate itself, but I'll check I have the chain through to the root certificate - I'm assuming that's what you mean?
Kind regards
