Answer:
If you see this error message, you cannot connect to our license server to verify your license.
Please ask your IT department to check the communication with our server. It is necessary to enable the following access in the firewall policies as well as in the network:
- Server name: lm.dlubal.com
- Server IP: 89.187.130.211
- Server Port: 443
If the connection still does not work after this procedure, your IT department needs to check whether the SSL certificate has been exchanged, based on your internal guidelines (for example, using a proxy). Sie sollten dies mit einer Software (z. B. OpenSSL) in der Kommandozeile prüfen können:
- cd C:\Program Files\OpenSSL-Win64\bin
- openssl.exe s_client -connect lm.dlubal.com:443
