nrpe is the listening utility on a server waiting requests from the nagios server .
It has a "access limiter" as to make sure that only one server can query it , that is 
the "allowed_hosts" directive .

If your nagios ip is changed - and the local machine  ip hasn't , then you need to tell the local 
machine the Nagios server has a  IP so it will accept the requests from the new ip .

this is done by replacing the nagios server ip in the allowed_hosts directve (you have it as 
122.xxx.xxx.xxx) .
