VirtuBox I'm having the same problem. I can't create 2 sites on the same VPS. I ran the command wo site update site.tld -le=clean and gave the error in nginx,
nginx: [emerg] cannot load certificate "/etc/letsencrypt/live/site.tld/fullchain.pem": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/letsencrypt/live/site.tld/fullchain.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file)
nginx: configuration file /etc/nginx/nginx.conf test failed
The second site always gives error in SLL it does not open stating that I am using the certificate of the first. What am I doing wrong?
