1. Complete the whole process in one go

Once on your launcher, click once on “Log in with Browser“, then fill in carefully and do the flow to the very end.

2. Deactivate your firewall/antivirus/VPN

Some antivirus, firewalls, or VPNs can block the access to your Launcher.

In that case, we recommend:

Opening the corresponding ports from your firewall

• Whitelisting Shadow on your antivirus: your antivirus may also call this an exclusion or exception. The instructions may vary depending on your antivirus software. Please contact your antivirus provider or visit their website for more information.

• Deactivating your firewall/antivirus/VPN, connecting to the launcher, and reactivating your firewall/antivirus once you’ve successfully started your Shadow.

3. Make sure your browser’s cookies are up to date

• If you are using a browser extension (such as Adblock or Hush), verify that this one is not blocking the cookies.

• Clear your browser's cache and cookies. You can check this article to get the instructions depending on your web browser.

4. Enable Web Push Notifications on your web browser

Shadow is using web push notifications in the authentication process. If you do not receive them, they might be disabled in your browser permissions.
In that case, we invite you to reset your browser permissions by following the instructions from this article: Guide: Enable push notifications on Chrome, Firefox and Safari

5. Re-sync your local clock

Once you have logged into your browser, if you click on “Open Shadow” and nothing happens, this might mean that your local date and time are not synchronized correctly on your device.

To synchronize them correctly, we invite you to refer to the following instructions depending on your operating system:

​

6. Try connecting with another web browser

Your browser by default might block the authentication process. To identify whether it is causing the issue, you can try connecting with another web browser: Google Chrome, Mozilla Firefox, Safari, etc.
If this doesn’t resolve the issue, please try:

• Turning on Incognito Mode on your web browser

• Connecting with another device

7. Uninstall and reinstall your Shadow PC app

You can follow the instructions from the article How to uninstall your Shadow PC App according to the application(s) you are using.

This will ensure that there are no issues with your files.

8. If nothing works, contact the Support
