Ethernet not working in Mac OS Sur

Ethernet network does not work in any of the ethernet ports. WI FI is fine. Any solution for this problem?

MAC Big Sur version 11.1m (20C69)
MacBook Pro (Retina, 13-inch, Mid 2014)

I have a Plugable brand Thunderbolt 3 dock that was working until installing 11.2 beta 2. Now it can't get a DHCP lease and self-assigns an IP address with no connectivity.
