Error loading document second time

I’m using a community document server and develop a vue project and nextcloud to create an file-browser-client which can open files with onlyoffice (pdf, docx, …)

Generally I can select a file in my filebrowser, I dynamic create a config for onlyoffice, and the file opens.
Then, I close the editor and click on another file - and I’ve got an error:

If I close the editor again and select the first file - everything is ok.

If I reload my app I can open every file correctly, but closing and opening another file will give the error again.

Summary: After loading my app I can open one random document. After closing I cannot open any other document.

DocumentServer:
Debian Linux Server
Docker 28.5.1
onlyoffice/documentserver:latest (should be 9.1.0-168)
Running on a public subdomain, directly connected to the internet
I cannot find any relevant errors in any server log file.

VueApp with “@onlyoffice/document-editor-vue”: “^1.6.1”

Reduced my code to minimum:
<DocumentEditor
id=“docEditor”
:documentServerUrl=“documentServerUrl”
:config=“config”
@events_onDocumentReady=“onDocumentReady”
@onLoadComponentError=“onLoadComponentError”
/>

A working config-Object:
{
“document”: {
“fileType”: “pdf”,
“key”: “101030559”,
“title”: “Nextcloud Manual.pdf”,
“url”: “/nc/apps/onlyoffice/download?doc=eyJ…shortend”,
“isForm”: false

A non-workding config-Object:

If needed I can send you credentials to the app where you can tryout the error by yourself.

I dont know why, but when I tryed solving the problem the next day - without any changes - it works perfectly.

Hello @diegroupware
