# Troubleshooting

## Troubleshooting `connection refused` messages

These usually result from Electron failing to start. This is frequently a result of a misconfigured system (e.g., missing required shared libraries or not having a display server running).

To debug, make sure that the Electron process is able to start. The path to the electron executable depends on your environment, but you can obtain it easily:
```
print(Blink.AtomShell._electron)
# /Users/travis/.julia/packages/Blink/mwJC9/deps/Julia.app/Contents/MacOS/Julia
```

Running that executable from the command line (outside of Julia) should open an empty Electron window, or it should print out an error message.

For error messages of the form `error while loading shared libraries: libasound.so.2`, make sure you've installed that shared library using your system's package manager (e.g., `apt install libasound2`).

If you still can't solve your problems, please feel free to open a new issue.
