Internet radio and Pi Zero W - unable to gain web access to VLC

I have a Pirate Radio kit and have the basic internet radio functionality working fine. However, I want to access VLC via its http/web server interface, but I can’t connect no matter which browser I use nor whether I try from the Pi itself or some other machine on my local network. In all cases, I get a username/password request, but no combination (even null) of values seems to work for me, and after a few tries I get redirected to a VLC page with 401 Client Error.

Recent posts that I have seen suggest that nobody else is having a problem with this. Any suggestions?

You have tried just a blank username and “raspberry” as the password?

Even if you change the password due to SSH, the VLC web server is hosted from a seperate user, which uses “raspberry” as it’s password.
