Websocket connection failed

Hi,

I installed ShinySDR on a Raspberry Pi.

when I try to access the we interface from my tablet in the same local network, I get the

WebSocket connection failed (retrying).
If this persists, you may have a firewall/proxy problem.

error.

I assume I don’t have a firewall/NAT issue, because I’m in the same network, nevertheless it’s not working.

My config uses ports 8100, 8101.

nmap doesn’t show an open port for WS:
