tls ... how to configure to make it working ?

[Bjaris]

Hi all, I a just beginning to use Grafana & I decided to use as datasource MQTT with Mosquito brocker on Windows configured like this :

listener 8884
protocol mqtt
require_certificate false
allow_anonymous true

cafile C:\Program Files\mosquitto\certs\mqtt_ca.crt
certfile C:\Program Files\mosquitto\certs\mqtt_srv.crt
keyfile C:\Program Files\mosquitto\certs\mqtt_srv.key
tls_version tlsv1.1

Grafana is on a Linux 22.04 VM and I configured the MQTT Data sources plugin like this: URI : tls://192.168.0.108:8884 Username : tester Password:

After a Save & Test : error connecting to MQTT broker: network Error : x509: cannot validate certificate for 192.168.0.108 because it doesn't contain any IP SANs

Look like a cetificate probleme & I tried to modify grafana.ini to give the cert file but with no chance yet. How to proceed i.e. where should I put certificate and what to modify ? Thx in advance.
