"Failed to call resource" error when fetching data from a specific host

“Failed to call resource” error when fetching data from a specific host.
I can’t understand these results. Only certain hosts experience this.

Hosts with “Failed to call resource” errors cannot retrieve data, but
All other hosts are working fine.

  • Docker Container
  • Zabbix : 5.4
  • Grafana : 8.1.0 or latest
  • Zabbix Plugin : 4.2.1

This is my log. Deleted IP and time zone…

Hi @Nirsa

Can ytou provide more details please? Are you saying that the zabbix plugin was working and now it’s not, or that some of your Zabbix endpoints are working while others are not?

Consegui resolver este problema habilitando a opção “Desabilitar alinhamento de dados” no Data Source do plugin do Zabbix.
