Troubleshooting
Solutions to common issues when setting up and using Nexting.
Verification Issues
HTTP 404: Not Found
The verification endpoint couldn't be reached on your domain.
Ensure vercel.json (or equivalent) is in your project root
Deployments can take 1-2 minutes. Check your hosting dashboard for status.
If your project has a path prefix (e.g., /blog), ensure it's included in the source path: /blog/__verify__
Try visiting https://yourdomain.com/__verify__ in your browser
Project Key Mismatch
The verification endpoint returned a different project key.
Go to Settings and copy the configuration again. The project key may have been typed incorrectly.
If you have multiple Nexting projects for the same domain, ensure you're using the correct key.
Page Display Issues
"Project Not Found" Error
The proxy couldn't find an active project for the given key.
- Complete the verification process in Settings
- Check that the project status is "Active"
- Ensure the project key in your configuration matches exactly
"Page Not Found" Error
The project is active, but the specific page doesn't exist or isn't published.
- Check that the page exists in your Nexting dashboard
- Ensure the page status is "Published" (not Draft)
- Verify the path matches exactly (case-sensitive)
- If using a path prefix, ensure it's set correctly in both places
Wrong or Old Content
The page shows outdated content after you've made updates.
- Content is cached for up to 5 minutes — wait and refresh
- Try a hard refresh (Cmd/Ctrl + Shift + R)
- Clear your browser cache or try incognito mode
Configuration Issues
JSON Syntax Error
Vercel deployment fails due to invalid JSON.
Common mistakes:
// ❌ Wrong - trailing comma
{
"rewrites": [
{ "source": "/a", "destination": "..." }, // <- trailing comma not allowed
]
}
// ✅ Correct
{
"rewrites": [
{ "source": "/a", "destination": "..." }
]
}Conflicting Routes
Your app has a page or API route at the same path as a Nexting page.
- Remove or rename the conflicting file in your app
- Use a different path prefix for Nexting pages
- Note: Rewrites only apply when no matching file exists
