I’m in development and started `dfx start`  
After a potentially long run, a large number of local development containers are running  
dfx service will report an error

```auto
hyper::Error(
     Connect,
     ConnectError(
         "tcp connect error",
         Os {
             code: 111,
             kind: ConnectionRefused,
             message: "Connection refused",
         },
     ),
)

```

Is there any way to deal with these errors without cleaning the container data?

Hi,I meet the same error a few days ago.  
Then I reinstall cargo and dfx in “sudo su” mode.  
When everything is installed. I run “source $HOME/.cargo/env”, and then run “dfx start”.  
Finally, it works.  
But I don’t know whether it works for you.
