Unable to login on DF 2.14

Hi after many months I’m no more able to login to my dreamfactory UI page.
When I insert my username and my password and click “Login” button nothing appear, no error and notification are displayed.
In Dreamfactory.log there is no evidence of any password or login issue…please could you help me to understand how to debug this problem ?

Hi Luca. Did you try resetting your password? Use the “Forgot Password” link on the login page.

Hi, yes I have tried but I don’t recevie any email. It seems that there is no answer from GUI when I click on the button ( login button or Request password reset ).
How can I check more in deep ? In log files I don’t find any issue.
