[Bug] wrong network warning in explore page

[xihale]

Network is on work, but it still displays the following warning.

I highly believe that it should be displayed "loading" info.

In fact it doesn't mean you network doesn't work.
Instead it means you are not able to connect the web data scoure

That's my habits on GitHub.(Which means that I should think more before submitting my comments.)

By the way, both are ok with me.
