Grandstream ATA will not register

Have been helping new customers with a Grandstream ATA, model GS-HT-801

Last week there were no problems.  Within a few mins of configuring the unit and rebooting, it came on line and could be used

Tried two today and these keep reporting "Offline"

The configuration is the same...

The 087xxx number

The password as shown

Is there anything I should be looking at?

1. You can try the IP instead of the server name IP is
2. NAT Traversal needs to be set to keep alive
