Try checking this post first:

> [@Cannot connect to (custom) board](https://discuss.pynq.io/t/cannot-connect-to-custom-board/603):
>
> I managed to build the pynq sd card for a custom board. I connected the board to my home router with the ethernet cable and to a laptop with the USB. I could see the boot log, everything apparently fine. From the laptop I could ping the board at 192.168.1.8 (found with ifconfig, I expected another fixed value !?). But… a browser (chrome) to that IP (or pynq:9090) only shows a blank page and an error message… what can be wrong?

If this doesn’t help, please post details of what you have tried, and what is not working.

I directly connect the board to windows host pc through ethernet. i set the ip address as per the docs. i used the chrome browser and gave the [http://192.168.2.99:9090](http://192.168.2.99:9090). it is not working.  
how do check my ethernet connection is working properly

Did you try ping?  
Did you try check ifconfig?  
Did you check if Jupyter is running?

All in linked post, try read through it and check the various steps.
