the server and port not shows after click the extension in status bar

[lollipop190]

after i click the extension in status bar, the preview is shown as expected, but the server not shows up.
i wonder if it's my problem?
p.s. the "reveal-markdown" extension of vscode, which is a fork of vscode-reveal, works very well.

Some time there are conflit with other extension for space in bar. Maybe that's it.

i think it's not the problem of space ? since i turn off a lot extensions in status bar, but the server is still gone...
