Generally you should not use the archive directory. The current ssl files are symlinked so that is what should be used. For nginx I think the cfg statements would be:

ssl_certificate /etc/letsencrypt/live/www.example.tech/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/www.example.tech/privkey.pem

Afraid I don't know what the haproxy equivilent would be.
