Client not always reconnect after disconnection

[fmartingr]

I have a very basic setup for a PoC:

       var subscribeConversation = function() {
           swampdragon.subscribe('chat', 1, {chat_id: 1}, function (context, data) {
               // any thing that happens after successfully subscribing
               console.log(context, data);
               if (!firstRun) {
                   swampdragon.getPagedList('chat', {chat_id: 1}, 1, function (context, data) {
                       data.reverse().forEach(function(item){
                           addMessage(item.author, item.message);
                       })
                   }, function (context, data) {
                       console.error(data);
                   });
                   firstRun = true;
               }

           }, function (context, data) {
               // anything that happens if subscribing failed
               console.log(context, data);
           });
       }

       swampdragon.open(function(){
           addMessage('SYSTEM', '----- Connection OPEN --------------------------------------');
           subscribeConversation();
       });

       swampdragon.close(function(){
           addMessage('SYSTEM', '----- Connection LOST --------------------------------------');
       });

       swampdragon.onChannelMessage(function(chanel, data) {
           console.log('New channel message');
           addMessage(data.data.author, data.data.message);
           console.log(data);
       });

With two browsers open, when I first load the page there is no problem, but if I close and open the socket sometimes one or both clients dont reconnect to it.
