Can't connect to private docker registry

Hello!

I'm trying to connect TeamCity to private docker registry (Harbor), but receiving an error:

From Web UI: Test connection to https://my-docker/v2/ failed: Unable to get authentication token, please verify username and password

From server logs: 

 WARN [' {id=1}; http-nio-8111-exec-7] -   jetbrains.buildServer.SERVER - Unable to find token in docker auth server response: '{

  "token": "a lot of random symbols",

  "expires_in": 1800,

  "issued_at": "2019-07-03T12:05:12Z"

}'

I saw this issue on TeamCity issues, but the status is "Fixed".

My TeamCity version: TeamCity Professional 2019.1.1 (build 66192)

Maybe someone has fixed it somehow?

Thanks!
