pytest-xdist ssh: Pseudo-terminal will not be allocated because stdin is not a terminal

Question

I'm trying to run remote test (very simple hello world test) execution using pytest-xdist. I'm trying to do it from Windows 10 cmd (not admin), the remote machine: Linux Centos 7.9 Tried to run tests locally - no problem.

The remote machine is reachable by ssh (using mingw)

This is how I run:

C:\\Python399\\Scripts\\pytest.exe -d --rsyncdir D:\\my_temp\\remote_test --tx ssh=-FD:\\my_temp\\remote_test\\ssh_config myvmmachine//python=/usr/bin/python3.6//chdir=~/my_py_test pytest_test.py

D:\my_temp\remote_test\ssh_config:

Host myvmmachine
  HostName 127.0.0.1
  User mydev
  Port 33556
  LogLevel DEBUG3
  IdentityFile ~/.ssh/my_rsa

After run I have following error:

D:\my_temp\remote_test>C:\\Python399\\Scripts\\pytest.exe -d --rsyncdir D:\\my_temp\\remote_test --tx ssh=-FD:\\my_temp\\remote_test\\ssh_config myvmmachine//python=/usr/bin/python3.6//chdir=~/my_py_test pytest_test.py

On the remote machine sudo systemctl status sshd -l shows there was no connection attempt

Could anybody help?
