So, recently migrated a UBUNUTU zabbix server, latest version, from ESXI to HyperV. The network card changed from ens32 to eth0, i changed this in the /etc/network/interface via nano, restarted and everything came back up without issues. . however, shorty after, all SNMP and Zabbix agents show they can't be reached. But yet, if I do a SNMP walk or a zabbix_get to the zabbix agents they get values fine. If I duplicate a host, it comes up via the zabbix agent, but I have a bunch of charts etc, that i don't want to rebuild. Any solution on how to get the old hosts to work.. They just state Network is unreachable..
