Problem with User Manager

Hello guys.
I have a routerboard 750, and I upgraded to ROS 4.15, and my problem is with usermanager.
I have at the same router user manager and a PPPoE Server ( ether1 ) and create users at usermanager admin page.
When I try to connect at the client I get error 691 ( username and password are correct ), but when I go at mikrotik logs, it said that Radiu Time Out.

I followed the guide at wiki page, and nothing worked.

Any help would be great.

Thnx.
