Re: [mosquitto-dev] Mosquitto SSL Error : Unable to connect (A TLS error occurred.)

I have installed a LoRa Server with the following services :
- MQTT Broker (*1.4.15*-0mosquitto1~xenial1)
- LoRa-Server
- LoRa-App-Server

On the other side, A raspberry Pi (with raspbian) send data with the LoRa-Gateway-Bridge.

When the connection is unencrypted (tcp://@server on the LoRa-Gateway-Bridge.toml), it works !

However, in ssl :

The client is connected :

/1524211792: New connection from on port 8883.//
//1524211792: New client connected from as 96240ae6-28cb-446c-8dd2-0d2d9f045487 (c1, k30)./

But it the server doesn't receive anything because :

/mosquitto_sub -h FQDN_OF_MY_SERVER -p 8883 -t "#"  --cafile /etc/lora-app-server/certs/CAcert.crt/

Did you recognize the slash (/) after the certificate?

/*=> Unable to connect (A TLS error occurred.)*/

The mosquitto logs shows :

/*1524212646: OpenSSL Error: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca*//* *//*1524212646: OpenSSL Error: error:140940E5:SSL routines:ssl3_read_bytes:ssl handshake failure*/

For information, it is an official certificate with CN = name of the FQDN of the server.
When i check it by openssl :

/openssl s_client -connect //FQDN_OF_MY_SERVER//:8883 -CAfile /etc/lora-gateway-bridge/certs/CECert.crt/

Same here and here it is called CECert.crt with an E?

*/=> Verify return code: 0 (ok)/*

I have seen in the archive that the same problem occured with older versions but not resolved...have you any advices to fix this issue ?
