Office.JS “This add-in is no longer available” error when creating a Word Document with context.application.createDocument()

Question

I'm developing an add-in for Microsoft Word 2016 using office js version 16.0.8626.1000. I use a web service to retrieve a document in base64 format and then I create a new Word instance with that.

The problem is that whenever I run the add-in from my server (not from visual studio debugger) it opens the document but the add-in frame displays an error

First Instance:

Second Instance:

This doesn't happen if I run the add-in from visual studio debugger, it opens the new instance without the frame.

This is my code

Office.initialize = function (reason) {
    // Checks for the DOM to load using the jQuery ready function.
    $(document).ready(function () {
        $('#get').click(function () {
            openWord();
        });
    });
}

This how I retrieve the document (without real url):

function openWord() {
    getDocumentAsBase64(function (data) {
        Word.run(function (context) {
            var myNewDoc = context.application.createDocument(data);
            context.load(myNewDoc);

            return context.sync()
                .then(function () {
                    myNewDoc.open();
                    context.sync();
                })
                .catch(function (myError) {
                    //otherwise we handle the exception here!
                    updateStatus(myError.message);
                })
        }).catch(function (myError) {
            updateStatus(myError.message);
        });
    });
}

function getDocumentAsBase64(callback) {
    $.ajax({
        url: 'http://myurltomydocument.com/getFile',
        data: "{}",
        dataType: "json",
        type: "POST",
        contentType: "application/json; charset=utf-8",
        success: function (response) {
            callback(response.d);
        },
        error: function (response) {
            updateStatus(response.d);
        }
    });
}

EDIT -- 8/12/2017

This is the manifest that I'm currently using if anyone wants to replicate the problem with Office 2016

I don't read Spanish, but the error mentions Visual Studio. I think Office is still trying to run a version that was sideloaded with Visual Studio and it's telling you that it can't do that. The problem might be the manifest. I notice that it still has the string ~remoteAppUrl in many places. When you are debugging with VS, this string is automatically replaced with the localhost URL, but you need to manually change all these to your web service's domain and sideload the new manifest when you are going to run it from the web service.

EDIT 12/11/17: If that doesn't fix it, try clearing the Office cache. Details are at: Clear the Office cache

Edit 12/19/17: Try this:
Go on File->Info->Check for Issues -> Inspect Document -> Inspect. Then on Task Pane Add-ins click Remove All
