seems the test example store uploaded file in folder named as client’s ip, how to specify the document.url then ?

my code:

const openDoc = function (body, node, file) {
    const url = ''
    const DOC_NAME = uuid() + '.docx'
    console.log('upload to oo as file ' + DOC_NAME)
    var formdata = new FormData()
    formdata.append('uploadedFile', file, DOC_NAME)
    formdata.append('fileName', DOC_NAME)
    var requestOptions = {
        method: 'POST',
        body: formdata,
        redirect: 'follow'
    fetch(url, requestOptions)
        .then((res) => {
            const script = document.createElement('script')
            script.id = ''
                config = {
                    document: {
                        fileType: 'docx',
                        key: 'Khirz6zTPdfd7',
                        title: '${DOC_NAME}',
                        url: '${DOC_NAME}'
                    documentType: 'word'
                var docEditor = new DocsAPI.DocEditor('${node.id}', config)`)
        .catch((err) => {

In our test examples files created/uploaded by users are stored in directories named after the IP address from which the user accessed the example. You may change the way the documents are stored in any way you wish. In your case it seems your IP has changed and you are no longer able to open the file. Do you use any proxy/VPN?

Yes I am using a http proxy, but document server is listed in “no_proxy” variable.

Also I noticed that is actually the address of docker0 interface.

don’t know why onlyoffice trying to find my file under that folder(

I have inspected how the example UI works using chrome dev tools, found that when it create
DocsAPI.DocEditor, a useraddress= is added as URL parameter. but I think it’s generated from server side, but I do all things in pure javascript, it’s also tricky and unreliable to get local IP address in javascript.
