How to connect to my web app running on mac over WiFi? I have very recently switched to mac, so i am a bit lost here...

I am running a test web app (Spring Boot app) on my mac now and I need to connect to it over WiFi form another device.

Now, when the app was running on win I could connect on

https://192.168.0.106:8080


(the IP address of the new mac is 192.168.0.102) but if I go to  https://192.168.0.102:8080 I get only "This page is not available"....

Thanks for your help!
There could be a few reasons, but your security settings are probably the most likely candidates.

Temporarily turn Off the Firewall

The easiest way to test this is to (very) temporarily turn off your firewall:

System Preferences > Security &amp; Privacy > Firewall > Turn Off Firewall








Retest your connectivity, if it works, turn your firewall back on and then allow the app through the firewall.
