Error since change of Router

[Summer2016]

Hi. Am using Version 9.0 and I got a DNS error, bu cannot identify it. I get the message : "task failed error the remote name could not be resolved"... From the Server side, it is possible to resolve the vcenter name. Where could/should I start the troubleshooting? Thx..

Could you explain a bit more where you get this error? Is this when running a backup job? Can you correctly resolve the hypervisors hostnames if so?

Oh, sorry for late reply. This was the message I receive in my mail notification. I can ping the hostname, but receive an IP6 name

Could you disable ipv6 on the VBR server and see if it then works?

This works !!!!!!! fine !

[nielsengelen]

Great. So all backups are working fine again?

They are just in backup process. This did not start before. So it looks fine. So, the problem is with my network an ipv6...
