New NBN installation has no connection

[yuanqin99]

A technician came to instlal NBN around 13:00 and it was working right away after installation, I had access to internet with 46Mbps download speed. 

10 mins after the technician left, the connection ligth on the NBN box started flashing red and there's no internet connection ever since. 

When I followed the troubleshooting guide and checking NBN outage at (https://www.nbnco.com.au/support/network-status), it shows my address is NOT connected to NBN. 

Is it normal ? any help would be appreaciated, thanks

@BasilDV  Sorry to ping you directly, I'm a bit despearte here, any help you can provide would be much appreciated here. I understand your entire support team is WFH to overcome the COROV-19, I'm doing the same here and that's why I need the internet to WFH.
