If you're running this server, you need to make sure the following header is being added:

Access-Control-Allow-Origin: *

For example in nginx:

```

server {

listen 443 default_server ssl;

listen [::]:443 ssl;

http2 on;

server_name example.com www.example.com;

ssl_certificate /etc/nginx/ssl/live/example.com/fullchain.pem;

ssl_certificate_key /etc/nginx/ssl/live/example.com/privkey.pem;

include /etc/nginx/ssl/options-ssl-nginx.conf;

ssl_dhparam /etc/nginx/ssl/ssl-dhparams.pem;

location / {

proxy_pass http://192.168.100.16;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header X-Forwarded-Proto $scheme;

add_header 'Access-Control-Allow-Origin' '*'; # <----

}

}

```
