Not connecting to Local host

I’m trying to set up a server connection for a new project but I can’t even get the preview to work properly. When I click on project settings>targets and I try testing the local host connection, it fails and says it " cannot find the uploaded files! Probably wrong path in web server url: http://localhost:3000 " Please help

Make sure your project folder points to the root of your web site, often ftp can point to a level above. When you hit test wappler uploads some files to your server then makes a http request for them. Sounds like yours are going to the wrong place
