This is my first time posting here, but I just started to play around with my new Raspberry Pi 3B. I have configured my Pi into a wireless access point and when I connect to the Pi, a NoDogSplash captive portal appears allowing me to connect to the internet. I am also trying to host an express server that the splash page will be able to access. I can currently run the server without a problem and when I SSH into the Pi and run "sudo telnet localhost 4000" I am able to connect to the server. However, when I connect to the access point on my desktop, I am unable to reach the server through the browser. Does anyone have any suggestions on how to fix this?
