Why Is iCloud Having a Connection Error?

The error message reads, “iCloud encountered an error while trying to connect to the server.” That simply means iCloud failed to establish a connection with iCloud servers. The issue is sometimes temporary, and simply reloading the page might get you signed into iCloud.

    It could also be due to factors beyond your control: poor internet connection, iCloud server downtime, web browser bugs, etc. The troubleshooting recommendations in this tutorial should help you regain access to iCloud in no time.

    1. Check iCloud Server Status

    Server downtime can trigger the “Connection Error” when accessing iCloud on the web. Visit Apple’s System Status page and check the status of iCloud Account & Sign In and iCloud Web Apps (

    system status

    You should be able to sign in to iCloud on the web if there’s a green indicator next to these services. A red or yellow indicator means the server is experiencing downtime or temporarily unavailable.

    There’s a great chance of encountering the “Connection Error” message if these iCloud services aren’t operating normally. Report the downtime to Apple or wait until Apple fixes the server outage.

    Note: You could have trouble accessing iCloud if any iCloud-related services (iCloud Drive, iCloud Backup, etc.) are unavailable.

    If all iCloud servers are online, the “Connection Error” issue likely stems from your internet connection or web browser.

    2. Troubleshoot Your Internet Connection

    Test your connection by reloading the iCloud web page and other open tabs. Visit different websites, download a file, or watch a YouTube video. There’s nothing wrong with your internet/network connection if your browser loads websites, videos, and file downloads without issue.

    Otherwise, reboot your router or switch to a different Wi-Fi network if you have trouble accessing the internet. Escalate the issue to your service provider if you still don’t have internet access.

    Many Windows users turning off Internet Protocol Version 6 (IPv6) in their connection settings resolved the iCloud connection error.

    3. Check Your Device’s Date and Time Settings

    Incorrect date and time settings can prevent your browser from establishing a connection with some websites. Ensure your computer’s date and time are accurate, and synchronize the time with an internet time server. Also, configure your computer to set its date and time automatically.

    Go to Settings > Time & language > Date & time and toggle on Set time zone automatically and Set time automatically.

    Reload the iCloud tab in your browser and check if you can sign in or access your files.

    4. Update or Try a Different Browser

    Try signing in to iCloud using a different web browser to rule out browser-specific malfunctions. Say you’re getting the iCloud connection error in Google Chrome; switch to Microsoft Edge, Firefox, or Safari. There’s likely an issue with iCloud servers if the connection error is prevalent across all browsers.

    If you can sign in from a different browser, update the browser that cannot connect to iCloud. Clearing iCloud’s cookies and site data in the affected browser could also resolve the connection error.

    Open your browser’s cookies and site data settings page and type “icloud” in the search box. Delete entries in the result, reload the iCloud tab, and try signing in again.

    Reset the browser to factory settings if it still won’t connect to iCloud’s server.

    More Troubleshooting Tips

    If the “Connection Error” isn’t due to server downtime from Apple’s end, these troubleshooting tips should resolve the issue. Restart your browser or computer if the error continues.

    Use the iCloud app to access your files if all efforts to sign in to iCloud on the web fail. If you have a Windows computer, install iCloud from the Microsoft Store and sign in with your Apple ID. On Apple devices (iPhone/iPad/Mac), check the iCloud Drive in the Files app or Finder to access your files.
