Sage 300 v2023 external web screen error Undefined after entering login

Question

After upgrading to Sage 300 from v2022.4 to v2023.1, we get an Undefined error after entering the login screen from external web screen. his issue is only with external access outside the network. Internal web screens are fine. I have reviewed KB 77607 (Setting up Sage Web Screens) and KB 117661 (Error: Undefined), but these have not helped to resolve problem. Any thoughts?

I discovered this error began occurring with version 2023 of the Web Screens. It would appear to be the result of improved security on Sage's part. The cause of the error for me was accessing the login screen from a different URL than that published in the underlying SSL certificate. In version 2024, this error was improved further with an actual message being returned instead of "Undefined". In version 2024, the error reads as: " The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel." 
 In version 2023, I could immediately work around the "undefined" error by accessing the site over port 80 http externally (this was via a secure VPN) until the problem with the external subdomain and SSL mismatch was rectified. The cause may not be the same for you but if you're using an internally signed SSL and users are accessing the site using a different IP or hostname externally, it may be the cause. You could try switching back to port 80 http briefly to test if the error goes away externally (perhaps do this after hours with production databases offline for security).
