Ошибки CORS в pouchdb

Я получаю ошибки CORS в Firefox и Chrome, но не в cURL. Вот мой cURL:

curl -H "Origin: http://mymachine:8080" https://wamoyo.cloudant.com/simpsons -v

Это моя команда, вот вывод:

Хорошо, теперь браузер все еще возвращает эту ошибку:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://wamoyo.cloudant.com/simpsons/_changes?timeout=25000&style=all_docs&feed=longpoll&since=35-g1AAAAEjeJzLYWBgYMlgTmFQTElKzi9KdUhJMtPLzc_PK87IzEvVS87JL01JzCvRy0styQEqZUpkSLL___9_VgZTIn8uUIA9zcQ81cgkCdUIY3xGJDkAyaR6qCmsEFOMkxMTUy1RTTHCZ0oeC5BkaABSQIP2g0ziApuUYpJmZmZqjmqSKWGTDkBMQnKTuVFymoFxUhYAK3pbEA&limit=25&_nonce=7YzIfmsBHKTHaGPq. This can be fixed by moving the resource to the same domain or enabling CORS.

Когда я запускаю функции синхронизации или репликации PouchDB.

PouchDB.sync('https://wamoyo.cloudant.com/simpsons/', 'simpsons', {live: true})
  .on('change', onChange)
  .on('complete', onComplete)
  .on('error', onError);

function onChange (info) {
  alert('onChange running');
}
function onComplete (info) {
  alert('onComplete running');
}
function onError (err) {
  alert('onError ' + err);
}
