So at home I connected the grove pi to my network and was able to connect with the IP address (didn’t have the cable for the ethernet/usb for my powerbook). All good.
Now, at work just directly connecting via ethernet cable and I get a 404 error.
Apache/2.4.235 (Rasbian) Server at dex.local Port 80.
Terminal ssh login works, but get 404 with IP address too.
