Hello, I have strange issue regarding to Zabbix agent connectivity, I believe.
After adding new VM to serwer and installing Zabbix Agent there,
Zabbix monitors problem shown below, from time to time :
I can ping from X.X.X.X to Zabbix server without any problems.
Also, on X.X.X.X firewall (UFW) is not enabled, so nothing is blocked on this side.
What is even stranger, the error message I see for some minutes, time to time, and then, for about 10-15 minutes it is okay. Then again, it crashes, and so on.
On the same HW server where X.X.X.X is, there is another VM, let's call it Y.Y.Y.Y (teh same OS, Ubuntu 16.04) with no problems at all. So I believe these are not network issues.
But, when I try to nmap port 10050 from X.X.X.X to Zabbix, I get info that "host is down". Nmaping Zabbix from Y.Y.Y.Y shows that port 10050 is open.
How to solve this?
