Unable to see Grafana on 2nd commuter - same network

I have Node Red, Influxdb and Grafana installed on a W10 computer, all is well on that computer. However I’m unable to get the Grafana dashboard to load on a second computer (W10) on the same network.
Both Node Red and Influxdb dashboards work ok on the 2nd computer
I’m using the format but just get an error site can’t be reached - the ip address is definitely correct.
Any suggestions?
