Issue Overview
In specific network environments, users may encounter difficulties connecting Magics to the floating license server, resulting in inaccessible licenses for Magics, MatConvert, or plugins. This issue has been observed starting with MatConvert 11.x (in combination with any Magics version) and Magics 29.x itself. While the License Administrator may display valid licenses, Magics remains unable to retrieve them. Additionally, MatConvert or plugin functionality may remain unavailable despite an established connection.
Root Cause
This issue arises in floating license setups where a Fully Qualified Domain Name (FQDN) or hostname (e.g., "fls.materialise.net" or "localhost") is used to connect to the server. The problem is caused by DNS resolution failing to translate the domain name or hostname to the correct IP address required for communication.
Workaround
To resolve this issue, replace the FQDN or hostname with the server's corresponding IP address in the License Wizard. This bypasses DNS resolution and establishes a direct connection to the server.
Example Replacements:
-
fls.materialise.net→10.11.12.13 -
localhost→127.0.0.1
Steps to Apply the Workaround
- Open the License Wizard in Magics.
- Locate the server connection settings.
- Replace the FQDN, hostname, or "localhost" with the server's actual IP address.
- Save the changes and restart Magics.
By following these steps, you should be able to successfully connect to the floating license server and access all licensed functionality.
