Android emulator can no longer connect to localhost

Question

I have a server on my computer running on localhost:8080 , previously I was able to access this in the Android emulator under 10.0.2.2:8080 and it worked great. I went to load it again at some point today and it no longer works. No configuration has changed to my knowledge.

I can still access localhost when I use a browser on my computer, so the server is still running okay. But on the emulator, whether using my app or a browser it will not connect.

Any suggestions would be appreciated. Thanks.

Answer 1

In case anyone comes across this in a search, this is how I fixed the problem:

1. Open terminal and enter sudo nano /private/etc/hosts
2. Delete the line ::1 localhost
3. Ctrl-O then enter to save. Ctrl-X to exit.

Restarted my local server and after that it worked.
