Zabbix 5.0 strange behavior
Hi everyone,
I have recently stumbled upon a strange behavior. There are 2 pictures attached.
here is my proxy configuration:
and the agent of one of the monitored machines:
The server can connect to the proxy. If i telnet to it the connection lasts about 3 seconds then it's closed by the proxy. Same goes for the proxy.
So first why i don't have the ZBX label green on my hosts? Second, why is the host configuration behaving like that? i have never set any DNS discovery nor anything like that. As you can see the configurations are plain and simple.
If you have questions please feel free to ask, i'll be glad to provide all the answers.
Thank you in advance

So first why i don't have the ZBX label green on my hosts? Second, why is the host configuration behaving like that? i have never set any DNS discovery nor anything like that. As you can see the configurations are plain and simple.
If you have questions please feel free to ask, i'll be glad to provide all the answers.
Thank you in advance
