Firewall settings for Lightning licenses
When Lightning starts up, it connects to our license provider to see if you can use the product. This happens when you:
- Request a trial license
- Activate a license
- Check out / check in a license
If you get an error message about your internet connection, that could mean two things:
- You really have no internet connection.
- A firewall blocks the request to our license provider.
If your internet connection works correctly, you need to add a few exceptions to your firewall. Please allow connections over port 443 to these IP addresses:
- 20.82.170.150
- 23.102.21.212
If adding these exceptions does not fix your issue, please check out How to fix license issues.
