Cannot access resource with Zero Trust

I have setup my zero trust tunnel - I want to be able to RDP to 192.168.1.158.
I have set my default Warp client profile to include ips and domains under split tunnel.
I have a single split tunnel entry destination: address 192.168.1.158/32

However I can’t ping or rdp to the computer after connecting with the Warp client, what should I try next?
