Jupyter notebook server timeout

[virgosystems]

I followed instructions here to expose Jupyter notebook over LAN , which had previously worked on Raspbian. However, on Armbian the browser returns ERR_CONNECTION_TIMED_OUT. The client is win11. To the best of my knowledge, no firewall (iptables or nftables) is installed.  

 

Many thanks for any help

ETA: local loopback via lynx (at given IP, not localhost) connects without error

Network connection itself works? Checked lsof for correct listen?
