HTTPS fails

Do you want to: Suggest a featuI followed the guides to make my project work with https and everything went pretty well, except that now I have errors that I don’t understand. I am attaching a development console image.

Everything was perfect and now I’m getting two errors:

WebSocket connection to 'wss://-------------/7.1.1-23/doc/46/c/264/kegp1b1u/websocket' failed:

Hi @fedeamandi :wave:

WebSocket connection to

Generally, this error means that a connection with a WebSocket has been closed due to a particular error.
However, it’s difficult to say what causes it by the screenshot you have provided.

  • Could you specify if you are proxying the requests within your network?

Have you used our instructions for using ONLYOFFICE Docs behind the proxy?

Mixed Content: The page at

This error occurs when data is transferred from a service with HTTPS to a service with an HTTP connection. This is insecure and all browsers block this type of data transfer.


In most cases, this issue depends on the proxy settings and how you’ve configured your network.

It’s surprising that you’re using version 7.1.1. The current version of the document server is 8.0.1.
