Please check the VIBs... It could be you're missing one or more on your newly installed host.

Have you connected esxi host back to dvswitch and assign proper vmnics to uplink? Also, the portgroups as you said are standard portgroup or dvswitch port group? If possible share the screenshot of vswitch or dvswitch connectivity.

After you add the newly installed host to the inventory the first step is to make sure the host is compliant with the host profile. Then add it to the cluster and to the Distributed Switch. When you keep the host in maintenance mode you can fix any errors before you migrate workloads to that host.

@Nawals, build of ESXi the same, like another hosts. In my humble oppinion, this firewall rules (their absence) blocks some control-plane traffic for DVSwitch and VMs cannot to use network after migrarion. So, first, I need to apply profile and rules. Then need to check VMs connectivity through DVSwitch. I cannot to understand why firewall rules does not applying...

I didn't understand why you asked "So what happens when you try to remediate the host?" if I wrote it in my first message. May be this is my language troubles, sorry.

Could it be that you are missing some VIBs on the newly installed host? Please compare two hosts with esxcli software vib list

Because applying a profile is not the same as remediating a host... When you apply a profile you see errors as the host is not compliant. When you remediate a host you try to make the host compliant to the profile by changing host configuration settings.

jburen​, you right. I found difference in some vibs. One of them is

esx-nsxv6.5.0-0.0.7563456

I installed it and then, profile applied correctly. DVS is working fine now.

Cause of this trouble, I think, incorrect removal of the NSX.

In any way, you helped me a lot. Thank you very much...
