Hi @Yoshiki,
I’m glad you renewed the cert but keep in mind that you will have this problem next time you want to renew the certificate, so you could add a pre-hook and post-hook to stop nginx before the renewel and start it again once the cert has been renewed or maybe you could switch from standalone to webroot authentication so you don’t need to stop/start nginx and you only add a deploy-hook to reload nginx once the certificate is renewed so it is loaded into nginx.
Cheers,
