The issue has been reproduced and a fix should be deployed ASAP.

A fix has just been deployed, it should resolve the issue.

Please note that you don't need to use the workaround for the docker.sock file (it was a misconfiguration on sphinx-preview's side).

Please also note that you need to run sphinx-preview on an Atom instance only opened on your Sphinx project (it will fail if you have several project folders opened on the same Atom instance).

Finally, if the project does not refresh on change, please check if configuring a sphinx-server.yml configuration file at your project root fixes the issue (see https://github.com/dldl/sphinx-server).
