> Check the controllers to ESX connectivity ?

   Please run the below command on ESX host. if it returns esx and controller ip address that means connectivity is fine

   esxcli network ip connection list | grep 1234

   if above command doesn't return anything then please restart netcpad service

/etc/init.d/netcpad restart

   Also look into below KB article.. it may helps you.

    In previous comment, Screen-shot looks fine to me. I guess restarting netcpad service should resolve your issue.

Hi,

it difficult to provide solution with single screen-shot.

1. Can you please check VM is connected to correct logical Switch?

2. If possible please provide the screen-shot of DLR interfaces?

3. Is it test environment? It was working before??

4. Check the controllers to ESX connectivity ?

Check the communication health from the UI Check Communication Channel Health and do a Force Sync Services this is same as restarting the netcpad but you can do it on a cluster level

If that doesn't help, check the NSX Controller Cluster status and try to do Update Controller State
