Unable to login Root or web on ESXi

I am evaluating Nextcloud solution but I am facing several issues,

  • After installation is finished and network is configured, I tried to access the web interface, but cannot access not even ping is reachable.
    I tried to login to the console to check the Network interface through the command line, but whenever I write the correct username and password, the console is rested again (clear the screen and ask for username and password again). I though that I am writing the wrong username and/or password, but when I intentioally write a wrong password, I got a message saying that the username password are incorrect.
    But when i type the correct username and password the same issue happens, the console is cleared and I am asked again to write the username and password.
    Any help
