Cannot run test remotely in Visual studio 2017

Installed: TestAgent 2017, TestController 2017. Firewall: Disabled everywhere. Wrote test:

public void TestMethod1()
{
     Assert.IsFalse(false);
}

Try to run this test on remote agent from VS 2017 and get in the output:

No connection could be made because the target machine actively refused it

TestController log:

I, 6516, 45, 2018/01/23, 14:49:37.723, WINTCNN\QTController.exe, ControllerObject: Creating ControllerExecution for TestRun a007769d-4e55-4dc9-8d5a-db42b5b3f10e

And nothing more related to test execution

When I try the same test from VS 2015 everything goes OK. And TestController log has many more records.

What prevents my test from executing from VS 2017?
