Download Failed

Everything fine on server, I can work with documents and excels. What’s causing the trouble through web application?

Hi @Alikhan :wave:
Could you please provide the following information:

  1. The version of your Document Server.
  2. Please try running the following commands and check for any errors:
  • wget [your-document-server-address] from your storage application server.
  • wget [your-storage-address] from the Document Server.
  1. The Document Server logs located at /var/log/onlyoffice/documentserver/ (inside the container). If the logs contain sensitive information, you can upload them to an external storage service and send me the link via a private message.
