v6.5 Linux Agent unable to connect to ERA

[V2TW 3]

Hi There,

I have a customer with Linux version of ERA Agent and File Security for Linux installed. However for some reason agent will not connect to ERA server. Upon closer inspection it looks like in agent trace.log ERAAgent process is constantly crashing when trying to start NetworkModule with "Host not found":

The server has no connectivity to the internet, and ERA server is specified as IP address, with no firewall in between. The server is being used as an internal nameserver.

logs from info_get command is attached, we tried re-installing but it's not helping, please help to check.
