Check Internet Connectivity
As per Microsoft’s Support team, the Error Code 0x8004de40 occurs when the user has a bad or weak internet connection. So, the first thing we are going to do is to check whether our internet is working properly or not. First, if you are using a wired internet connection, then check the plug and whether it is properly connected or not. Plug out the LAN cable from the RJ45 port and then plug in again, and reset the router using the physical button in the router. Second, if you are using a wireless connection via WiFi, then try opening a few websites and check your internet speed via third-party tools like SpeedTest.net or Fast.com.
Enable TLS Settings
TLS or Transport Layer Security is the successor to the old SSL or Secured Socket Layer. If you don’t know what SSL is, let me explain it via a live example. When you visit a website, you will notice a lock in a green-colored bar in the URL bar, just before the website URL. That lock means the website is secured to put in your personal details (if required), and a 128-bit encryption technique protects the website. So, in this solution, we will enable the TLS so that the browser connects to the TLS protected websites. Without TLS, OneDrive might be facing a connection error. To do so, follow the below steps,
Open the RUN window by pressing the Windows Key + R simultaneously.
Now, type inetcpl.cpl and hit enter to execute the command to open the Internet Properties window.
Now, go to Advanced Settings, scroll down to TLS settings, and enable the TLS 1.0, 2.0, and 3.0 settings. And finally, click Apply and then Ok to save the modification.After that, restart your system and then try opening OneDrive.
