error: No such host is known

[gustavouehara]

We are configuring backup for 2 VM with "Veeam Agent for windows" after first try the job finished with error "No such host is known" in both servers.
other similar error cases in forum point to ports and dns resolution , there isn´t a FW and resolution is throught Host file.
my case for support is 03138515.

thanks

Hello gustavouehara,

Are you talking about agent managed by backup and replication server? How this hosts were added to Veeam B&R console (what protection group type was used)? Thanks.

Hello Dima P

Yes the VAW is managed by Veeam and replication server,
Both VM are added to a Protection Group as Individual Computers

thanks

Did you use IP address or host name while adding these VMs to protection group? Thanks.

Finally the incident was resolved by Veeam Support.
problem:was related to dns resolution
resolution: edit FQDN name at host file on source and Veeam server.

Thanks for your help... Changing DNS to another working DNS server saved me
