SSL cert not renewing (DigitalOcean)

Hey,
my SSL cert is expiring in 10 days and it did not auto-renew.

I’ve tried using:
/etc/letsencrypt/acme.sh --cron --home /etc/letsencrypt > /dev/null

But I got this error message:

mysite.com:Verify error:Invalid response from http://mysite.com/.well-known/acme-challenge/dYla8wY4VX-nN70ie2iH8Sjdqr0r0HnFZ-bJl0LAUWg

I don’t know if it helps, but here’s my nginx config:

## mysite.com.conf
server {
    listen 80;
    listen [::]:80;

    server_name mysite.com;
    root /var/www/ghost/system/nginx-root; # Used for acme.sh SSL verification (https://acme.sh)

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $http_host;
        proxy_pass http://127.0.0.1:2368;

    }

    location ~ /.well-known {
        allow all;
    }

    client_max_body_size 50m;
}

and

## mysite.com-ssl.conf
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name mysite.com;
    root /var/www/ghost/system/nginx-root; # Used for acme.sh SSL verification (https://acme.sh)

    ssl_certificate /etc/letsencrypt/mysite.com/fullchain.cer;
    ssl_certificate_key /etc/letsencrypt/mysite.com/mysite.com.key;
    include /etc/nginx/snippets/ssl-params.conf;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $http_host;
        proxy_pass http://127.0.0.1:2368;

    }

    location ~ /.well-known {
        allow all;
    }

    client_max_body_size 50m;
}

Any help much appreciated.

I’m having issues as well with the DigitalOcean droplet. Ghost config didn’t automatically start up upon initial ssh login.
