i'm sorry for late reply. i was going through body detoxification. 

only primal clients should use wss://cache2.primal.net/v1 for number of reasons. your local cache instance is available at ws://127.0.0.1:8801 (this is default address on which server is listening which can be changed). if you want to expose the cache instance to public you should use nginx or some other webserver which can do reverse proxy and provides TLS for security.
