Can't connect to server

I’ve installed docker and brewpi on my raspberry Pi and connected to my spark v3. I get all the way to the end of the page on the wiki and get the container list as expected but when I click on the published port I get the “can’t connect to server” message.
The Pi and spark are on the network. The spark is connected to the Pi via USB and the Pi is connected to the router via ethernet.
I must have missed something and apologise if I’m being dumb, any assistance greatly appreciated, thanks

many thanks for the quick reply, Elco. I’ll try again tonight.
