Can't get Let's Encrypt to register a new account

When I try to register basically any email address via the built-in client on a loadmaster running, I get the following error;

Acme: Problem connecting to; return code 7 (code: 3)

Any ideas for next steps? Is there a way to get better failure information via the CLI? Additional logging that could be turned on?

The error message you're encountering, "Acme: Problem connecting to; return code 7 (code: 3)," suggests an issue with the LoadMaster's ability to connect to the Let's Encrypt ACME server for certificate registration or renewal. This issue can occur due to network connectivity problems, DNS configuration issues, or firewall restrictions. To troubleshoot and resolve this issue, you can take the following steps:

1. Network Connectivity:

  • Ensure that the LoadMaster has proper network connectivity to the internet. Verify that it can reach external websites and resources without issues.
  • Check if there are any network proxy settings or firewall rules that might be blocking outgoing connections to Let's Encrypt servers. Adjust firewall rules as necessary.

2. DNS Configuration:

  • Confirm that the DNS configuration on the LoadMaster is correct and can resolve the Let's Encrypt ACME server's hostname ( to the correct IP address.
  • Test DNS resolution using tools like nslookup or dig on the LoadMaster to verify that it can resolve the ACME server's hostname.

3. Time Synchronization:

  • Ensure that the LoadMaster's system time is accurate and synchronized with a reliable time source. Let's Encrypt's servers often require accurate time for certificate operations.

4. Proxy Configuration (if applicable):

  • If your organization uses a proxy server for internet access, verify that the LoadMaster is configured to use the proxy server for outgoing requests. Check proxy settings and authentication, if needed.

5. Firewall Rules:

  • Review the firewall rules on the LoadMaster and any intermediate network devices. Ensure that there are no rules blocking outbound connections to the Let's Encrypt ACME server.

6. Additional Logging:

  • To get more detailed information about the issue, you can check for additional logs or enable more verbose logging if available on the LoadMaster. Depending on the LoadMaster's specific software and configuration, you might be able to adjust logging levels to capture more information about the failed connection attempt.

7. Let's Encrypt Service Status:

  • Occasionally, Let's Encrypt may experience service disruptions or maintenance. You can check the Let's Encrypt status page ( for any ongoing issues or maintenance that might affect certificate issuance.

8. LoadMaster Software Updates:

  • Ensure that the LoadMaster is running the latest firmware or software updates. Sometimes, updating the LoadMaster's software can resolve compatibility issues.

9. Contact Support:

  • If the issue persists after checking the above steps, consider reaching out to the LoadMaster's support team or Let's Encrypt support for further assistance. They may be able to provide specific guidance or solutions tailored to your environment. clover dashboard login

By systematically addressing these potential causes, you should be able to diagnose and resolve the issue preventing the LoadMaster from connecting to Let's Encrypt for certificate registration.

If you're having trouble registering a new account with Let's Encrypt, there are several common issues and solutions you can explore:

  1. Firewall or Network Issues:

    • Check if there are any firewall or network restrictions preventing your server from reaching the Let's Encrypt servers.
    • Ensure that your server has internet connectivity, and there are no issues with outbound connections.
  2. Rate Limiting:

    • Let's Encrypt has rate limits to prevent abuse. If you've hit a rate limit, you may need to wait before attempting to register a new account again.
    • Review the Let's Encrypt rate limits documentation to understand the limits and how they may affect your registration. 
  3. Check DNS Configuration:

    • Make sure that your server can resolve the Let's Encrypt API endpoint. DNS resolution issues can prevent successful registration.
    • Verify that there are no issues with your DNS configuration.
  4. Firewall Rules on the Server:

    • Ensure that the firewall on your server allows outbound connections on the necessary ports (e.g., port 443 for HTTPS).
  5. Check Server Time:

    • Confirm that the system clock on your server is accurate. Let's Encrypt performs time-based validation, and an incorrect server time could lead to issues.
  6. Update Certbot or ACME Client:

    • If you're using Certbot or another ACME client, ensure that it is up-to-date. Older versions might have compatibility issues with Let's Encrypt servers.
  7. Review Error Messages:

    • Check the error messages you receive during the registration process. They can often provide insights into the specific issue. 
  8. Use Alternative ACME Clients:

    • If you are using Certbot, consider trying alternative ACME clients like or lego. Different clients may have varying compatibility with Let's Encrypt servers.
  9. Check Let's Encrypt Status:
