A Let's Encrypt Misadventure

I recently started on a seemingly straightforward task: transferring a domain to a new server. While the process itself was relatively simple, I encountered an unexpected roadblock when attempting to obtain an SSL certificate from Let's Encrypt.

After successfully updating the DNS records for the main domain, I initiated the certificate acquisition process for both the main domain and its www subdomain. However, I was met with a series of cryptic error messages. Despite numerous attempts and troubleshooting efforts, the issue persisted.

Hours later, a moment of clarity struck. I realized that while I had updated the DNS records for the main domain, I had inadvertently overlooked the www subdomain. This oversight resulted in a mismatch between the DNS records and the certificate request, leading to the frustrating errors.

Key Takeaway:

When transferring domains and obtaining SSL certificates, it's crucial to meticulously review all DNS records, including subdomains. A seemingly minor oversight can lead to significant delays and headaches.

By sharing this experience, I hope to prevent others from falling into the same trap. Always double-check your DNS settings to ensure a smooth and successful certificate acquisition process.
