Portal authentication loops

0

I have just installed a new instance of webcon.
On the first screen Authentication in the portal, when I enter the admin password, the application clears the password field and nothing happens. There is the same reaction as when I do it through the browser.
I enter the correct password, because if I enter it incorrectly, I get a message about it.

When I do it locally on the server via the localhost name, it is ok.
When I do it from another computer, there is no response.

What is the problem?
