Localhost Can't assign requested address

I use MacOS 10.14.6 and few days ago I faced with a problem on my computer with localhost. Rubymine can't connect to database with an error "java.net.NoRouteToHostException: Can't assign requested address (Address not available).". Also when I run puma server on 0.0.0.0:3000, browser can't open page on this address, and when I run server on 127.0.0.1:3000, browser can't open page on this address too, but can open on localhost:3000. I ran ping and got this output:

PING 127.0.0.1 (127.0.0.1): 56 data bytes

Solution

  • WARP was the cause of the problem. Issue started after disabling the app. Disabling and reboot or enabling the app resolved the issue.
