After a reboot it takes 10-15 minutes to reconnect. Before the update it was 30 seconds.
I can connect to the core via it’s ip address.
The networking gear is still teh same/ Modem/router -> Bonn N8 switch.
Thanks for expanding on the error state. Can I please ask that you reproduce this behavior by rebooting your ROCK core and then manually send us a copy of your ROCK logs by using these instructions? The best way to get the logs over to us would be Dropbox/Google Drive.
