In C9, what is the equivalent address of localhost:3000


I see that it is some like a combination of “workspaceName”+dash+ “username”+“”+“3000” but its not working.

Anyone see what I’m doing wrong, or point me to the reference?



It’s not working because only ports 8080, 8081, and 8082 are open. run the app on port 8080 and it’ll also be publicly accessible on port 80. the url is right, just not the port.


Thank you.

I noticed one other small detail that may catch people up. My user account is myname_1 (underscore) but the URL it became myname-1 (dash).
