I was having a few problems with renewal (old certificate was being used despite being out of date), and in a sudden and stupid rush of blood to thehead I deleted the /etc/letsencrypt/live/ directory. When I try to run certbot --nginx i get errors like this
Prep: Error while running nginx -c /etc/nginx/nginx.conf -t.
nginx: [emerg] cannot load certificate "/etc/letsencrypt/live/bangorcomputer.co.uk-0001/fullchain.pem": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/letsencrypt/live/bangorcomputer.co.uk-0001/fullchain.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file)
nginx: configuration file /etc/nginx/nginx.conf test failed
How do I get rid of the cert errors and re-install a cert?
