Full details of the error message you see, or a detailed description of the problem you experience.
Unable to open Jupyter on host device, device is connected to wifi via ethernet, host pc is connected via WiFi. I am using cutecom serial console and UART connection between device and host to log.

I can ping the boards dynamic IP from host computer, I can also ping the pc from the device. I can however, not ping the boards static ip, which is 192.168.2.99, which is how I connect to JupyterLab. I noticed that in existing solutions communication was most not possible from board to host pc due to firewall issues, this is not the case here.
Going to https://192.168.2.99 or https://192.168.2.99/lab or https://192.168.2.99:8888 doesn’t work either.
Checking Jupyter status, seems to suggest everything okay on the jupyter end.

I set up my static IP through the GUI by going to WiFi>MyConnection>IPv4> and providing address, subnet mask, and gateway, as well as making DHCP to 8.8.8.8, 8.8.4.4. Which is different method than what the Assign your computer a static IP address suggests.
So first I checked my Ip a and ifconfig -a on host computer.

And edited the interfance file using
sudo gedit /etc/network/interfaces
Output:
auto lo eth0
iface lo inet loopback
iface eth0 inet static

netmask 255.255.255.0

I noticed this only includes my eth, not WiFi which is how my board would ping to the device, any help here is highly appreciated!
