【问题描述】：

我正在尝试将本地 PouchDB 实例与 Google App Engine 上的远程 CouchDB 实例同步。

我有successfully logged in to the remote instance，但是当我尝试同步时出现以下错误：

replication paused (e.g. user went offline)
pouchdb-6.3.4.min.js:9 GET https://<ipaddress>:6984/pouchnotes/ net::ERR_CONNECTION_RESET

同步功能

PouchNotesObj.prototype.syncnoteset = function (start, end) {
    var start = new Date().getTime();
    document.getElementById("syncbutton").innerHTML = "Syncing...";

    var i, 
    that = this, 

    options = { 
    doc_ids:['1450853987668']   
  };

    if(start){ options.startkey = start; }
    if(end){ options.endkey = end; }

    PouchDB.sync(this.dbname, this.remote, { retry: true })
    .on('change', function (info) {
       console.log('change');
        document.getElementById("syncbutton").innerHTML = "Sync Notes";
    }).on('paused', function () {
       console.log('replication paused (e.g. user went offline)');
        document.getElementById("syncbutton").innerHTML = "Sync Notes";
    }).on('active', function () {
       console.log('replicate resumed (e.g. user went back online)');
        document.getElementById("syncbutton").innerHTML = "Sync Notes";
    }).on('denied', function (info) {
       console.log('a document failed to replicate, e.g. due to permissions');
        document.getElementById("syncbutton").innerHTML = "Sync Notes";
    }).on('complete', function (info) {
      console.log("Sync Complete");
      document.getElementById("syncbutton").innerHTML = "Sync Notes";
      that.viewnoteset();
      that.formobject.reset();    
      that.show(that.formobject.dataset.show);
      that.hide(that.formobject.dataset.hide);
      var end = new Date().getTime();
      console.log("Time Taken - " + (end - start) + " ms");
    }).on('error', function (error) {
      console.log("Sync Error:" + JSON.stringify(error));  
      alert("Sync Error:" + error);
      that.showerror(error);
    });   

}

编辑添加：我需要设置吗？

【解决方案1】：

原来是I had not configured the firewall correctly。

对于其他偶然发现此问题的人：您只需要 SSH 隧道即可访问 localhost 上的 Fauxton。您不需要它来访问 API。

如果您想要access the API via https, the port is 6984（而不是 5984），并且对于非 Google App Engine 服务器，您需要类似 Nginx set up to provide a SSL certificate 的内容。在 Google App Engine 上，提供了 SSL 证书。

但你仍然需要configure CouchDB to enable SSL。

Thanks to the guys at the CouchDB user mailing list for their input.
