A-102 / A-105 / A-106 - I can’t connect to the Shadow launcher


Sometimes, the Launcher can send back an error when you try to log into your Shadow. It can be caused by several factors. In this article, we will give you several tips to prevent and solve this kind of error:

1. Complete the whole process in one go
2. Deactivate your firewall/antivirus/VPN
3. Make sure your browser’s cookies are up to date
4. Enable Web Push Notifications on your web browser
5. Re-sync your local clock
6. Try connecting with another web browser
7. If nothing works, contact the Support

Note: Error codes are found at the bottom of the launcher:

  • You need an active subscription to log into the launcher. You will receive the following message by login in without an active subscription:


  • If you try starting Shadow just after subscribing, please wait while your Shadow is getting activated. You will receive an email entitled: “Good news: Your Shadow PC is ready!” in your inbox when your Shadow will be ready to use!

  • We invite you to use your Wifi or Ethernet connection rather than a 2G/3G/4G connection if possible when trying to connect.

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.

If you click several times on “Log in with Browser”, it will consequently open several tabs on your browser. Filling the wrong one can result in getting an error.

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.

We do not recommend using a VPN with Shadow. For more information, please refer to this article:

Can I use a VPN with 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:

Go to

icons8-windows-client-24.pngStart > Settings > Time & language > Date & time. Then click Sync now

  1. From the Apple menu, select System Preferences.

  2. Click Date & Time.

  3. Click the Lock icon.

  4. Select the Set date and time automatically checkbox. If you’d like to use a custom network time server, enter the domain name of the time server. One stable option is []

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

If none of the solutions above resolved your issue, please contact the support and provide in your message:

  • On which web browser(s) you are getting this issue

  • Which of the solutions above you have tried

  • A screenshot of the error message you get
