New Install - Invalid origin error

Support

In case anyone is interested this is an nginx "sites-available" reverse-proxy file that uses self-signed certs, diverts port 80 to 443, adds a bit of hardening and also logging. It does work with 2.0.6-beta.

 {
    listen 80;
    server_name joplin.example.lol;

    return 301 https://joplin.example.lol$request_uri;
}

server {
    listen 443 ssl http2;
    server_name joplin.example.lol;

    proxy_read_timeout 720s;
    proxy_connect_timeout 720s;
    proxy_send_timeout 720s;

    client_max_body_size 50m;

    # Proxy headers
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header Host $host;
    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;

    # SSL parameters
    ssl_certificate /path/to/certs/joplin.example.lol-cert.pem;
    ssl_certificate_key /path/to/certs/joplin.example.lol-key.pem;
    ssl_protocols  TLSv1.2 TLSv1.3;
    ssl_prefer_server_ciphers on;
    ssl_ciphers "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA HIGH !RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS";

    # log files
    access_log /var/log/nginx/joplin.example.lol.access.log;
    error_log /var/log/nginx/joplin.example.lol.error.log;

    # Handle / requests and redirect to a specific port on localhost
    location / {
       proxy_redirect off;
       proxy_pass http://127.0.0.1:22300;
    }
}

Replace joplin.example.lol with your domain and /path/to/certs/example.lol-cert.pem and /path/to/certs/example.lol-key.pem with the real thing.

Then, with the real thing, sudo ln -s /etc/nginx/sites-available/joplin.example.lol.conf /etc/nginx/sites-enabled/joplin.example.lol.conf

I got to this by butchering other examples, I am not an nginx expert.
