Why does my GitHub webhook keep failing with a 404 error?
A 404 error for a GitHub webhook typically means the target URL is invalid or unreachable. Verify the URL and make sure your server is live and accessible.
A 404 error for a GitHub webhook indicates that GitHub is unable to reach the target endpoint URL, usually due to an incorrect URL or server issues. Start by double-checking the webhook URL configuration in Settings > Webhooks to ensure there are no typos or formatting issues. Ensure the endpoint’s server is live and properly configured to receive webhook payloads; this includes allowing requests from GitHub’s IP addresses or domains if you have security settings. If you’re using a local environment, make sure it’s accessible externally by using tools like ngrok to create a secure tunnel. Additionally, check your server logs to confirm that it’s receiving and correctly handling incoming requests. Verifying these details should resolve the 404 error, allowing GitHub to communicate with your webhook endpoint effectively.
