Hello,

I am not sure but guessing it's due to `client_max_body_size` Please add ‘client_max_body_size xxM’ inside the http section in /etc/nginx/nginx.conf, where xx is the size (in megabytes) that you want to allow.

```
http {
client_max_body_size 20M;
}
```

If still same, try to update `post_max_size` & `upload_max_filesize` for your php configuration.

Thank you
