Possible Hiding Windows Error Handler

If you try to use the ipfs daemon command from the command line, you will get exactly this error.

ipfs daemon
Error: Message phone tcp No connectex: The connection could not be verified because the target machine was definitely rejected. “>

C:\Users\Vegard Post berg>http://127 ipfs daemon
Error:.0.0.1:5001/api/v0/version?enc=json&stream-channels=true: Dial tcp 127.0.0.Connectex: 1:5001: Failed to set parent because machine niche was actively failing.

I’m running on Das 10 because Windows 8.1 has been updated

EDIT: .remove ..Well, ipfs ipfs do init restarts the daemon, but I then ignore it.

C:\Users\Vegard Berg>ipfs daemon
Error: Post dial tcp Connectex: No, no connection could be established because the target machine was active rejected.
