Do you have the appropriate KMS DNS records published in your Active Directory DNS?

It will be looking for an SRV record called _VLMCS._tcp.yourdomain.com which should be setup with the following details

Make sure any firewalls and routers between your client server and KMS server allow traffic to port 1688 including any Windows firewalls themselves (especially the one on the KMS server).

I believe this info is still accurate:

Clients must renew their activation by connecting to the KMS host at least once every 180 days to stay activated. Once activated, the client computers attempt to renew their activation every seven days(by default). Download ntfs for mac os x. After each successful connection, the expiration is extended out to the full 180 days

Cmd Kms Activation Windows 10

As the renewals are automated you are better off leaving that port enabled in your network so you don't need to constantly remember to allow it and disallow it at random intervals. Once you get more than 1 or 2 servers you are constantly having to figure out exactly when the next scheduled check-in is. It's not worth the hassle.
