Having a decade of experience in managing servers, our Dedicated Engineers are familiar with the SSH errors. Now, let’s discuss how our Support Engineers fix this error.
Connection timed out
Recently, one of our customers approached us with the same error message.
Our Support Engineers started troubleshooting the error by checking if the zabbix is running or not by running the command.
ps aux | grep zabbixThen we ran the below command in agent host
tcpdump -i any -n tcp port 10050Then we saw that we were not getting the incoming packets.
After that, we opened the port 10050 through iptables.
iptables -A INPUT -p tcp -m tcp --dport 10050 -j ACCEPTFinally we restarted the zabbix agent to fix this problem.
Configuration error
We received the same error from another customer. However the fix was different.
The Zabbix IP address was not present in the agent configuration file. In this case we added the Zabbix IP in /etc/zabbix/zabbix_agentd.conf.
Then we restart the Zabbix agent service. And this quickly fixed the error.
