Hi,

 According to the error, there is no DHCP offer being received. Is your DHCP server in the same subnet as TEP or different? If it is in a different subnet, then configure the DHCP relay on the Gateway. Also, check for DHCP snooping if configured or not.

The DHCP server is on a different subnet. Should DHCP snooping be configured?

It is a good practice to enable it. But make sure to have DHCP relay configured as DHCP server on a different subnet.

I have confirmed from our network team that DHCP relay is already configured as DHCP server, issue still not resolved

Can you please share the screenshots of Uplink profile, Host Transport node profile with TEP information & DHCP relay configuration from the switch/router. Also, if possible do a packet capture.
