Before progressing towards solutions, our advice is to try these short workarounds that worked online for many users. But if the error persists, proceed towards solutions. The possible workarounds that can resolve or at least downsize the causes of error are listed below:

Solution 1: Configure Internet Proxy & DNS Settings

Proxy servers allow you to bypass some restrictions applied by your internet service providers while some organizations apply them to set a secure connection with the network. However, sometimes the incorrect proxy settings can create problems with the OneDrive application, leading to a connectivity error. Furthermore, Microsoft determines the Transport Layer Protection (TLS) to provide server authentication to the clients. The TLS 1.0 and above is a security protocol that aids in establishing encryption channels over the computer network as mentioned in the causes. The OneDrive application may not function appropriately when these TLS protocols are disabled. Therefore, we need to disable the proxy settings, enable the TLS protocols, and configure DNS settings correctly in order to rectify the problem. Many users were able to fix the problem by following this solution. Follow the steps given below:

Disable Internet Proxy Settings:

As stated previously in the causes, corrupt OneDrive installation will lead to the OneDrive Error Code 0x8004de40. Corrupt application files cause malfunction which not only stops the propagation of the application but also there is a strong possibility that it might corrupt your operating system files as well. Our researchers recommend resetting the OneDrive application which will restore it back to its default state, fixing all the changes that have been made to it by the user or by the application or system itself. This proved to be a helpful solution for many users online. Follow the steps given below to successfully reset the OneDrive application:
