Hi,
Sorry, I didn't reply earlier. I was traveling and I just got to settle down and open my laptop.
DON'T USE 127.0.0.1 or localhost.
PUT 0.0.0.0 <--- This should get you past that error.
Also, I never put the socket part. Just leave it empty and it should work.
Originally I had some errors but they should be fixed in the current version in GitHub.
Please try it out and let me know.
