For successful software authentication on a corporate network, allow access to https://iws.corel.com, the address of the Corel authentication server. Use port 443, with the following endpoint: https://iws.corel.com. If the sign-in dialog appears, ensure access to https://ipm.corel.com, https://idp.corel.com, https://wll741ba4c.execute-api.us-east-1.amazonaws.com/prod/getautheninfo, and https://account.corel.com for authentication.
To allow access to the Corel authentication server, you may need to modify the security settings in your proxy or firewall software.
