unknown PSK identity

[Janet Kew]

I get this error on zabbix server in /var/log/zabbix_agentd.log

1281:20210706:171748.842 cannot find requested PSK identity "server-one", available PSK identity "zabbix-server"
1281:20210706:171748.842 failed to accept an incoming connection: from 127.0.0.1: TLS handshake set result code to 1: file s3_srvr.c line 2768: error:1408B0DF:SSL routines:ssl3_get_client_key_exchangesk identity not found: TLS write fatal alert "unknown PSK identity"

So your Zabbix agent expects PSK identity "zabbix-server" but your Zabbix server tries to connect to the agent with PSK identity of "server-one". What happens if you correct either side of the configuration and use the same PSK identity value on both sides?

I'm trying to implement https://github.com/sleepka/zabbix-kubernetes-monitoring and after importing template to zabbix dashboard and attaching it to kubernetes cluster nodes (each node is on separate server, and zabbix server is on separate server) I get same error in the Dashboard under Availability: ZBX is red and says the same message as in the zabbix_agentd.log

on zabbix dashboard, on the host, under Interfaces I changed the IP address of the agent from 127.0.0.1 to the IP address of the server that hosts this agent and then I get another error:

Get value from agent failed: cannot connect to [[ip_address]:10050]: [4] Interrupted system call
