The discord update file is used to update the application when required. However, if the Windows firewall interferes and prevents the data that Discord needs to update itself, it will result in the Discord update failed. In response, the server sends the data to the application. When an application needs to update, it first needs to send a request to the server. Windows Firewall monitors the outgoing and incoming data that comes through the network. This mainly happens due to the interference of the built-in Windows firewall or corrupted discord update file. When this issue occurs, it means discord is unable to write a new update to the directory.
