hello, I'm trying to use the variable $host in this entry:

ssl_certificate /etc/letsencrypt/live/$host/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/$host/privkey.pem;

to potentially make one entry that fits multiple domains, but it is not possible
I think the variable $host is not parsed in this specific directive

nginx: [emerg] BIO_new_file("/etc/letsencrypt/live/$host/fullchain.pem") failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/letsencrypt/live/$host/fullchain.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file)

it would be great to be able to use it here.
Thanks
