Preview not working on workspaces


When I try to preview my running applications, I’m getting the following message:

The webpage might be temporarily down or may have moved permanently to another web address

This has only started happening lately, and it’s the same on all of my cloud9 apps.

Have I reached the limit on my number of apps? I have 15 projects of various complexities stored on the free account. Has the port changed? The config I’m using is:

app.listen(process.env.PORT, process.env.IP);

I appreciate the help.



Are you trying to use any VPN or any third party extension like ( on your browser?

This might be due to this.
