The issue itself is well-described here in comments. All credits go to nenkoru.
For some configurations it takes longer than 10 seconds to start receiving stream. I experienced it on Hyper-V machine as well. First few connection attempts always time out. Increasing FIRST_FRAME_TIMEOUT_SEC solves the issue. It looks like it takes about 15 seconds for my particular configuration to properly start. I believe changing timeout to at least 30 seconds looks reasonable.
