Question
Replit publish fails with "didn't open a port" but the app runs fine in the workspace
first time publishing anything. Express app, runs in the webview no problem. When I hit Publish it builds, then sits on "Promoting" for a few minutes and fails with:
Your app didn't open a port within the timeout.
Make sure your app is listening on 0.0.0.0 and the port in .replit
my server:
app.listen(3000, 'localhost', () => console.log('up on 3000'))any idea?
What I’ve tried
Asked the Agent to fix the deployment twice, it changed the run command to npm run start and then back to node index.js. Same error both times.
Not an answer but I had the exact same message last month, the 'localhost' part was the problem for me. Try taking it out. abdul_r · edited
