Hello Team,
I have installed the latest 7.4.2 elastic and kibana on centos 7 (I removed the previous version 7.0.0 completely before installing 7.4.2 ) my elastic is running fine, kibana status shows it is running but it does not load the kibana page on the browser I checked in the log and I see no error in kibana.stderr but I see a message in kibana.stdout that states "Error scheduling telemetry task" full message/log given below, please check and let me know whats is wrong with my installation, Thanks.
Please find the kibana log below.
