Hi,
I upgrade Zabbix 4.2 to Zabbix 4.4.4.Some hosts are working fine and gave all data to zabbix server.
But some hosts not connected.Some hosts working fine.
Same IP settings.
Get value from agent failed: cannot connect to [[xx.xx.xx.xx]:10050]: [111] Connection refused (Some hosts)
or
Get value from agent failed: ZBX_TCP_READ() timed out (Some hosts)
or
Received empty response from Zabbix Agent at [xx.xx.xx.xx]. Assuming that agent dropped connection because of access permissions
How to fix this issues.
Note: After migrating some graphs stop.
No data
