Try logging in again

From the Shadow PC launcher, click “Log in with Browser“ one time, then complete the login process until the end. Clicking the login button too many times can result in multiple login sessions starting, causing a conflict.

Use another browser

Your existing browser might have settings that are disrupting the login process. Switching to a different browser could temporarily resolve the issue.

If you don't already have an alternative browser, please download and install one, then make it your default. The Shadow PC application will automatically direct the login process to the new browser.

If this doesn’t resolve the issue, try:

• Using Incognito Mode on your web browser

• Connecting with another device

Uninstall and reinstall the Shadow PC app

Uninstall the Shadow PC app, restart your device, and reinstall the app. You can download and install apps from the downloads page or your account.

Deactivate your firewall/antivirus/VPN

Some antivirus, firewalls, or VPNs can block parts or all of the launcher. To make sure your software is compatible:

• Open ports on your firewall. Your firewall may not have the open ports needed to complete the login process.

• Whitelist Shadow on your antivirus. Whitelisting, or adding exclusions or exceptions. Contact your antivirus provider or visit their website for more information.

• Temporarily deactivate your firewall/antivirus/VPN. Connect to the launcher and reactivate your firewall/antivirus/VPN once you’ve successfully started your Shadow PC.

Turn off adblockers

Shadow PC uses your browser to authenticate your login, and adblock extentions, such as Adblock or Hush, can interfere with the process. Temporarily disable adblockers or whitelist https://shadow.tech/.
