How to Fix Let's Encrypt Not Working
Still can't connect even though the servers are green? The Let's Encrypt lag is likely on your end. Run through this quick checklist to get back online:
- Update Your ACME Client: Older versions of Certbot or other clients may use deprecated API endpoints. Update your ACME client to the latest version to resolve validation errors.
