unable to connect to Tor server: dial tcp 127.0.0.1:9051: connectex: No connection could be made because the target machine actively refused it.
Your machine refuses the connection at port 9051.
Can you verify that the tor service is running at this port ?
I believe the standard port for tor is 9001 and 9051. But this can be freely changed. It is just important that you connect to the same port where tor is listening.
