Ktor project localhost:8080 refuses to connect

Question

I was working on a ktor project and everything was working fine. I started the server and it was working fine on port 8080 but now for some reason suddenly it stopped working. I killed the task and tried everything, I'm not sure what's wrong. I tried to reinstall IntelliJ Idea and I'm still facing the same issue. I tried using 127.0.0.1 , 0.0.0.0 , localhost but none of them work idk what to do. I've wasted like 2 hours on this thing. I've tried changing port, blocking firewall and antivirus.

Answer 1

for Android Developers: if running the app on the android-studio-emulator, then replace http://localhost:8080/ with http://10.0.2.2:8080/

Answer 2

change 127.0.0.1(localhost) to your private ip like 172.30.1.59 if you use wifi. if you use fixed ip then use it. i have same problem, but solve it with this. Nice! cmd -> ipconfig -> use ip address
