Local device cannot connect to Greengrass Core

[zhangzz0413]

Running the greengrade local auth demo cannot connect to the greengrade core. The logs of the greengrass core are continuously printed in a loop:
2023-04-20T11:43:38.636Z [INFO] (nioEventLoopGroup-7-23) io.moquette.broker.metrics.MQTTMessageLogger: Channel Inactive. {}
2023-04-20T11:43:41.511Z [INFO] (nioEventLoopGroup-7-24) io.moquette.broker.MoquetteIdleTimeoutHandler: Firing channel inactive event. MqttClientId = null.. {}

The SDK demo keeps printing error:

[ERROR] [Transport_OpenSSL_Sockets] [openssl_posix.c:302] SSL_ connect failed to perform TLS handshake.
[ERROR] [Transport_OpenSSL_Sockets] [openssl_posix.c:721] Failed to establish a TLS connection.
[ERROR] [DEMO] [greengrass_demo_local_auth.c:370] Connection to the broker failed, all attempts exhausted.
[ERROR] [DEMO] [greengrass_demo_local_auth.c:906] Failed to connect to MQTT broker 10.0.78.18.

My steps are as follows:

1. Created a thing on the IoTCore and download the certificate and private key: Device_Certificate.crt, Device.key.
2. Set up core devices and deploy components on them：
   aws.greengrass.clientdevices.Auth
   aws.greengrass.clientdevices.mqtt.Moquette
   aws.greengrass.clientdevices.mqtt.Bridge
   aws.greengrass.clientdevices.IPDetector
3. Configure cloud discovery and used greengrass_auth_conf.json to set auth component, and set the correct 'certificateAuthority'.
4. Create the costomerCA on greengrass core:
   openssl genrsa -out ca.key 2048
   openssl req -x509 -new -nodes -key ca.key -sha256 -days 1826 -out ca.crt
5. Running demo:
   cmake -S . -Bbuild -DGREENGRASS_ADDRESS="10.0.78.18"
   -DROOT_CA_CERT_PATH="/home/zzz/cert/ca.crt"
   -DCLIENT_CERT_PATH="/home/zzz/cert/Device_Certificate.crt"
   -DCLIENT_PRIVATE_KEY_PATH="/home/zzz/cert/Device.key"
   -DTHING_NAME="test_gg_sub_thing"
   cmake -S . -Bbuild && cd build && make greengrass_demo_local_auth

Hi @zhangzz0413

Just posting update. I'll be looking into the issue, but need some time to get and set up a personal green grass core.

Hello @zhangzz0413,
I'm trying to reproduce your problem locally. Just to make sure do you have a greengrass nucleus running at a different terminal?
