﻿1. To quickly solve the problem, carefully read the guide that shows the error code: 
﻿1.1 Error: code 100 
This error means that the client cannot connect to Windows services.
The Internet Protection Service may be disabled or blocked due to incompatibility with other programs.
If there is a problem, the service will be restarted automatically every minute.
Troubleshooting:
To manually restart the service, proceed as follows:
1. Go to "Start" > "Run" > "Services.msc" (run it as administrator).
2. Locate "Internet Protection Service" in the list of services.
3. Right-click on the name of the service and then "Restart".
4. Check the status in the right-hand column.

Check whether port 443 is allowed outbound to "185.236.106.106" in this way:
1. Go to "Start" > "Run" and type "cmd".
2. Once the prompt opens, type "telnet 185.236.106.106 443" and press "Enter."
3. Check if the connection is rejected, accepted, or if there is a timeout.
4. If the connection is "refused," it means that port 443 is blocked, perhaps due to a wrong network configuration or third-party software blocking it in the PC.
