Charts and screens are not displayed

[shhegolev]

Good evening, I ask you to suggest who can do what, at the moment the graphs in zabbix have ceased to be displayed version 4.0.28, no configuration actions were performed, why suddenly it is not clear I have no deep knowledge of zabix. Please tell me where to dig?
