Zabbix proxy not sending data

[gferradas]

Hi, im trying to configure a zabbix proxy to monitor a single host. The host and proxy are in the same network, the server is in another

but when i configure the proxy and the agent on the host the server doesn´t receive any items and nothing i checked the conf in the agent of the host and the proxy.conf and everything seems to be okay.

And the logs of the proxy show this:

669182:20230428:140014.931 cannot send proxy data to server at "172.19.129.75": negative response "failed"

669182:20230428:140029.951 cannot send proxy data to server at "172.19.129.75": negative response "failed"

Also this in a testing area so for the moment i set selinux to permissive the proxy is in a rhel 9 and the host is a rhel 8

any ideas of what is happening?

Hi,

Did you make sure that the versions of the zabbix server and zabbix proxy are the same?

[gferradas]

Now that you say the proxy is 6.2 and the server is 6.0 but wouldn´t still work even if they are different versions?

[[email protected]]

No, the server and the proxy must be the same versions for it to work.

So, you should downgrade proxy or upgrade server.

[gferradas]

Ok, thanks for the help i will downgrade the proxy and see if it works thanks again

[gferradas]

Well i downgrade the proxy now it shows items in the dashboard but when i enter in latest data the server still doesn´t recieve information of the host

[[email protected]]

Can you put the logs of the proxy and the server here so we can check?
