@d-uzlov If you will run out of tasks then be free to check if this issue is actual :)
We got clock injection into netwrokservices and I hope it solved this problem, but we need to verify it.

[denis-tingaikin]

looks like the clock is not ready for sandbox. So this actually is blocked.

Seems like this should just work now.

Need to check this by enabling this test https://github.com/networkservicemesh/sdk/blob/8e964705e60431463c60b6de44d591f5ea605035/pkg/networkservice/common/refresh/client_test.go
