Some firewalls or settings from your company network might sometimes prevent you from accessing your services.

If you have trouble with starting Shadow, try connecting with another connection (e.g., sharing your cell phone connection) to see if the problem persists.

If using another connection solves your issue, it is very likely that your network settings are blocking the connection to Shadow. In this case, here are the steps to follow to open your Shadow connection:

How do I open the ports of my company network?

1. Open Windows Defender Firewall (on the Start menu, type "Windows Defender Firewall" and select it from the list of results).
   
   

2. Click on "Advanced settings".
   
   

3. Click on "Outbound Rules" then "New Rule...".
   
   

   This rule only applies to outbound connections.

   

   
   
   

4. Click on "Port", then "Next".
   
   
   
   

5. Click on "TCP" or "UDP" according to the protocol that you use.
   

   You can create another rule for either protocol later.

   
   

6. Click on "Specific remote ports" and type "8001-15299".
   
   

7. Click on "Next".
   
   
   
   

8. Complete the remaining steps in the window, then click on "Finish".
