Grafana error connecting to Zabbix Triggers

Hello good afternoon.

“Zabbix Triggers” is a communication with zabbix is local and is working normally, only this item occurs.

I already updated my version from 5.1 to 5.2, did not solve.

I changed browser, cleaned history, cache, according to some suggestions in github, but to no avail.

It follows the information of my environment.

Grafana Version: Update: 5.2.3 (commit: cf4c090)
Zabbix Version: 3.2.11

Error below:
Plugin Error
Fetch error: 404 Not Found Instantiating Loading Loading plugins/alexanderzobnin-zabbix-app/panel-triggers/module

I did a new install on another server, solved the problem me, temporarily. But I have curiosity in knowing how to solve this, I believe that uploading a new server is not the correct solution for the problem…
