Portal authentication loops

0

Hi,
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.

What is the problem?
where are the logs
