Firewall Can sometimes prevent synapse from starting properly if configured to block its internet connection. To check if Microsoft Defender Firewall is the culprit, you can disable it temporarily. See the guide on how to disable Microsoft Defender Firewall to apply this solution. When you are disabled, you can try to run Razer Synapse to see if it works without any problems.
If the software starts working with the firewall disabled, you can configure Microsoft Defender Firewall To allow Razer -Synapse through it. We have an article explaining how to allow apps through the Windows firewall, which will lead you in the process.
This potential solution also applies to third -party firewalls. You can temporarily disable your firewall or its Antivirus component to see if it solves the problem. If it does, you can add synapse to the firewall’s allowed app list.
