No internet connection after installing zabbix

[reza]

Hi dear fellows
Yesterday i installed zabbix on my ubuntu 18.04 and it works perfectly and there was no problem to access internet.
After restarting my laptop zabbix still working and ubuntu discovers and can connect lan and wifi networks but there is no internet connection.
I restarted network-manager service with clean netplan but it dosent work at all.
Is there some config or something i can change to solve this problem?
thanks

I really don't think that the issue is in any way related to Zabbix.

I didn't find any relation too, but I Uninstalled zabbix-server and agent, after reset network services there is no problem with internet.
This time i choosed docker installation and everything is OK.
Thanks
