Understanding Cloudflare Error 1016 – Origin DNS Error
Table of Contents
Before diving into the fixes, it’s essential to understand why Cloudflare Error 1016 occurs. This error typically indicates a problem with the DNS configuration of the origin server, preventing Cloudflare from establishing a connection. Some common causes of Error 1016 include:
1. Misconfigured DNS Records: Incorrect or incomplete DNS records can prevent Cloudflare from resolving the domain’s IP address.
2. DNS Propagation Delays: Changes to DNS records may take time to propagate across the internet, resulting in temporary connection issues.
3. Origin Server Unavailability: The origin server may be down or experiencing connectivity issues, preventing Cloudflare from establishing a connection.
4. Firewall or Security Settings: Firewall rules or security configurations on the origin server may block Cloudflare’s requests, resulting in connection errors.
Solution 1: Verify DNS Configuration
The first step in resolving Cloudflare Error 1016 is to verify the DNS configuration of the domain. Ensure that the DNS records are correctly configured and point to the correct IP address of the origin server. Follow these steps to verify DNS configuration:
1. Log in to your Cloudflare account and navigate to the DNS settings for the domain.
2. Review the DNS records, including A, AAAA, CNAME, and MX records, to ensure they are accurate and up to date.
3. Check that the A or CNAME record for the domain points to the correct IP address of the origin server.
4. If necessary, make any corrections or updates to the DNS records and save the changes.
Solution 2: Check Origin Server Availability
If the DNS configuration appears to be correct, the next step is to check the availability of the origin server. Ensure that the origin server is up and running and accessible from the internet. Follow these steps to check the origin server availability:
1. Ping the origin server’s IP address from your local machine to verify connectivity.
2. Check the origin server’s status using server monitoring tools or services.
3. Review server logs for any error messages or indications of connectivity issues.
4. If the origin server is down or experiencing issues, resolve the underlying problems and restart the server if necessary.
Solution 3: Flush DNS Cache
DNS cache on your local machine or network may contain outdated information, leading to Cloudflare Error 1016. Flushing the DNS cache can help clear outdated records and resolve connectivity issues. Follow these steps to flush the DNS cache:
Windows:
1. Open Command Prompt as an administrator.
2. Type the command `ipconfig /flushdns` and press Enter.
3. Wait for the confirmation message indicating that the DNS cache has been successfully flushed.
macOS:
1. Open Terminal.
2. Type the command `sudo killall -HUP mDNSResponder` and press Enter.
3. Enter your administrator password when prompted.
4. Wait for the confirmation message indicating that the DNS cache has been successfully flushed.
Solution 4: Disable Cloudflare Proxy (Bypass)
If Cloudflare’s proxy service is causing issues with resolving DNS records, you can temporarily bypass Cloudflare and connect directly to the origin server. Follow these steps to disable Cloudflare proxy (bypass) for the domain:
1. Log in to your Cloudflare account and navigate to the DNS settings for the domain.
2. Identify the DNS record (usually an A or CNAME record) associated with the domain.
3. Click on the orange cloud icon next to the DNS record to disable Cloudflare proxying (the icon should turn gray).
4. Wait for the DNS changes to propagate (this may take up to 24 hours) and then try accessing the website again.
