Problems with accessing jupyter notebook on linux

Hello. I am a bit of a linux noob. I am having some issues accessing my pynq z2 board (v2.5) using ubuntu 20.04. I can access my pynq Z2 board and jupyter notebook files in windows by connecting my board directly to my router and entering pynq:9090 in a web search bar then \pynq\xilinx in a file search window. this works fine.
When I try the same procedure in ubuntu I am unable to connect to the board via direct connection to the router. I was instead able to connect using a static ip by entering // into a firefox search bar which was great, but, when I try to access the board files by entering smb:// into a file search bar no file is found.
can anyone help me with this as I would much prefer to use the linux os.

Thank you
