Zabbix Proxy - Host not found & invalid field name "hosts.available"

[bigrig]

I have setup a Zabbix Container in Azure and connected that container into the on-prem and cloud network and validated DNS is working correctly.

At a high-level the issue is that I have deployed my Zabbix Agent to a server and am not receiving any availability data back to our Zabbix hub via the proxy.

The errors I am getting on the Proxy are:

• failed to update local proxy configuration copy: invalid field name "hosts.available"
• cannot send list of active checks to "X.X.0.X": host [HOST] not found (X isn't the actual value, nor is "HOST")

On the example agent I am getting a similar error:

• no active checks on server [PROXY:10051]: host [HOST] not found

First check if Zabbix server and Zabbix proxy are the same version.

That was exactly the problem! Thanks so much. It would be good if the proxy and the hub output that error message somewhere.
