Hello everyone.

Not full information you provided. 

Have you changed the DNS entry on the Domain controller? 

Check with nslookup command what will be the answer. If the problem was only there you are lucky boy.

Can you access it via IP? If so can you try use the cli to try dns lookups to see what is failing?

Have you try reboot the vCenter server VM?
SSH using the root password to reboot the VM. This will enable all the services to restart. There might be service that is haltering you to access the vSphere console

I solved the problem.

When the server was installed, the FQDN was not set, it was left blank. When I updated the network information, VAMI uses the hostname as the FQDN. I updated the hostname to blank and this solved the problem

As I told in the beginning - you are lucky boy. 

Last summer I had a request to change DNS on vCenter. The consequences were much more painful
