if you run commandline like this ss-local -c config.json --plugin obfs-local --plugin-opts "obfs=http;obfs-host=www.bing.com", but when you write to config.json like this plugin_opts not plugin-opts

Thanks, but confirm plugin_opts in config.json.
I will change simple-obfs to v2ray-plugin, later.

Thank you very much. How on earth were I supposed to know the syntax in config file is different. I have been trying to make it work for an hour.
