Comment:

 Hi cypherpunks. Are you running nyx with the same user as tor? Tor limits
 read access for its authentication cookie to its own user and the above
 error indicates a basic permission issue. Also, in your torrc you can
 [https://2019.www.torproject.org/docs/tor-
 manual.html.en#CookieAuthFileGroupReadable set CookieAuthGroupReadable] if
 you'd prefer to use group permissions to grant access.

 I'll keep this ticket open with two action items on my end...

 1. Adjust Stem's exception message to better describe what user/group have
 access.
 2. Add a Nyx FAQ entry about cookie permissions.
