It’s Time: Renew Your SSL Certificate Manually (Let’s Encrypt + Netcup DNS)

It’s that time again — the SSL certificate expired 😅 In this tutorial I’ll walk you through renewing an SSL certificate manually using Let’s Encrypt (Certbot) with Netcup as your DNS provider (DNS TXT / _acme-challenge validation). ✅ What you’ll learn: How to check your current certificate details How to confirm your domain’s name servers (Netcup) How to renew using Certbot manual DNS challenge How to verify the TXT record with dig (and avoid failed validation) Final browser check (incognito to avoid caching) ⚠️ Important tip: DNS propagation takes time. Don’t rush. Use the dig TXT check more than once — you may still see old values. In my case it took ~20 minutes.
