I’m having trouble with my Next.js app. The first time I ran npm run dev, everything worked fine. But now, when I try to start the development server again, it gets stuck and doesn’t load.
I’ve tried creating a new project, but I’m experiencing the same issue there too. Interestingly, my other React apps that don’t use Next.js are working without any problems.
I’m on Windows 10 and I’ve already tried killing the Node process, but that didn’t help. Here’s what I’m seeing in my terminal:
> [email protected] dev
> next dev
- ready started server on 0.0.0.0:3000, url: http://localhost:3000
After this, nothing happens. The server doesn’t start and I can’t access my app.
Has anyone run into this before? Any suggestions on how to troubleshoot or fix this issue would be really helpful. I’m kind of stuck and not sure what to try next. Thanks in advance for any help!
hey have u tried checking ur firewall settings? sometimes it can block next.js from starting properly. also, make sure ur antivirus isn’t interfering. i had a similar issue and turning off my antivirus temporarily fixed it. worth a shot if nothing else works!
I’ve encountered this issue before, and it can be frustrating. One thing that worked for me was clearing the Next.js cache. Try deleting the .next folder in your project directory and then running npm run dev again. This often resolves weird hanging issues.
If that doesn’t work, it might be a port conflict. Even though you’re seeing the ‘ready started server’ message, something else might be blocking it. Try running netstat -an | findstr 3000 to check if anything’s using port 3000. If so, you can either close that process or use a different port by adding “dev”: “next dev -p 3001” to your package.json scripts.
Also, make sure your Node.js version is compatible with your Next.js version. I once spent hours debugging only to realize I needed to update Node. You can check your version with node -v and compare it to Next.js requirements.
If none of these work, you might want to try creating a minimal test project to isolate the issue. Sometimes it’s a specific dependency or configuration causing the problem.
I’ve dealt with this exact issue before, and it can be maddening. Have you tried clearing your Next.js cache? Sometimes that does the trick. Just delete the .next folder in your project directory and run npm run dev again.
If that doesn’t work, it could be a port conflict. Even though you’re seeing the ‘ready started server’ message, something else might be hogging port 3000. Try running netstat -an | findstr 3000 to check. If something’s using it, you can either close that process or use a different port.
Another thing to check is your Node.js version. Make sure it’s compatible with your Next.js version. I once wasted an entire afternoon debugging only to realize I needed to update Node.
Lastly, if all else fails, try creating a minimal test project. Sometimes it’s a specific dependency or configuration causing the issue. Good luck!
