"Plugin health check failed" after Grafana restart

[Toha1997]

Hello,

I successfully installed the plugin today. I got no errors in the grafana.log file and try to configure the OPC-UA connection. I restarted the Grafana server because I could not connect to my OPC UA Server (due to wrong Opc UA settings). After the restart, Grafana outputs "Plugin health check failed" every time I press "Save & Test". Here is corresponding the grafana.log:

Thanks for your suggestion about another issue before，today I yarn install and yarn build|yarn dev successfully. But I make build failed ，it shows “make（e=2，The specified file could not be found ）”，then I try to connect to OPCUA server，I also meet the same error"Pulgin health check failed",I test it in win 7(64bit) and win 10, all cannot work.

Without a successful "make build" the backend component is not compiled. So that is why you get the Plugin health check failed. Unfortunately, I don't know why your "make" fails. Maybe the developers will comment as well 😄.

I reinstalled the plugin today and now everything works as intended 👍
