Cant establish secure connection

[Jamieh1979]

Trying to access Google classroom for my daughter and keep getting error messages. The attached is the message on safari but also get similar messages with Edge (your connection isn't private - NWT::ERR_CERT_AUTHORITY_INVALID)

I am guessing it is something to do with router or armor security settings because if I hotspot the mac to my phone it connects to the link.

Any help would be greatly appreciated.

try using googles dns at 8.8.8.8 or 8.8.4.4

or cloudfare at 1.1.1.1

it could be a dns issue with your isp

What modem do you have? 
What firmware is on the router? 

Do you have armor activated? 

Does any other device have issues or just the one? 

doe sit happen over wifi or wired?

Hi thanks for the reply

What modem do you have? R8000 (X6 AC3200)
What firmware is on the router? V1.0.4.66_10.1.75
Do you have armor activated? Yes
Does any other device have issues or just the one? Just the Mac and it appears to be just Google meet but may affect others sites

doe sit happen over wifi or wired? It's connected over WiFi, can't establish a wired connection due to location of devices

have you check if its armor blocking it?

Hi
It was my first thought that it was Armor blocking it but it is not showing up as being blocked by armor in the threat list. And I also disable Armor and still got the same error messages.
