I upgraded a server that lives on a 2019 Hyper-V. I upgraded from 2012 to 2019. The server now has a Bang over the network connection. I disabled the adapter and enabled the adapter, I changed from dhcp to static and still nothing. I created a new virtual switch but and connected to that but it did not help.
When I attempt to ping the gateway I get the error
PING: Transmit Failed General Failure
