We have several tutorials using /etc/letsencrypt/live for the certificate path, for example https://www.howtoforge.com/tutorial/securing-ispconfig-3-with-a-free-lets-encrypt-ssl-certificate/ where the commands are Code: ln -s /etc/letsencrypt/live/$(hostname -f)/fullchain.pem ispserver.crt ln -s /etc/letsencrypt/live/$(hostname -f)/privkey.pem ispserver.key With the new acme.sh implementation, these paths have changed. For the commands above, when using server1.example.com as hostname, it would be: Code: ln -s /root/.acme.sh/server1.example.com/server1.example.com.cer ispserver.crt ln -s /root/.acme.sh/server1.example.com/server1.example.com.key ispserver.key And for incron: Code: /root/.acme.sh/server1.example.com/ IN_MODIFY ./etc/init.d/le_ispc_pem.sh instead of Code: /etc/letsencrypt/archive/server1.example.com/ IN_MODIFY ./etc/init.d/le_ispc_pem.sh Same applies to https://www.howtoforge.com/securing...server-with-a-valid-lets-encrypt-certificate/ and probably more tutorials.
