I am using Zabbix Active Agent to monitor hosts over the network but getting "no active checks on server [xx.xxx.xx.xx:10051]: host [host1] not monitored." errors only in one host with same exact server/agent configuration as in other hosts. I have double/triple checked the hostname and other configurations but issue has not been resolved. I believe I must have broke something while working on Zabbix templates but not sure what I did. I noticed "cannot send list of active checks to "xx.xxx.xx.xxx": host [host1] not monitored" error in Zabbix server log. Please help.
No active checks on server [xx.xxx.xx.xx:10051]: host [host] not monitored

Best Answer
The host is disabled.
As you say that you are not using Zabbix proxy and host seems to be enabled, possible reasons that mask the problem:
Make sure to compare the name agent and server print in their logfiles with the
Hostnamefield in the host properties. Keep in mind that it is case sensitive.
