SOAP UI 5.4 and HP SM Rest. Using GET method gives 401 error

Hi, experts,

I use SOAP UI 5.4 to test REST ws of HP SM.

Created test REST project, set URI = ""

in HP SM I've done:

1. restaccessviabrowser:1 in sm.ini and restarted HP SM

2. RESTful API capability in operator table for <integr> operator - it's sysadmin as well

3. Restful checkbox is enabled in extaccess for probsummary table

in SOAP UI in Auth I've added Basic authorization and set login and password - used <integr> login

So, after all that steps when I push "play" button in SOAP UI Request, it gives me:

Fri Jan 11 18:24:03 MSK 2019:DEBUG:Connection closed
Fri Jan 11 18:24:07 MSK 2019:DEBUG:Attempt 1 to execute request

Fri Jan 11 18:24:38 MSK 2019:DEBUG:Connection closed

I have tried the same HP SM account in SOAP project in SOAP UI - it works correctly

what is incorrectly configured?
