When trying to export data from PTV Visum to PTV Visum Publisher (File > Export > PTV Visum Publisher), selecting data, selecting target scenario, and clicking export an error appears.
"The configuration for Visum Publisher could not be found. Make sure that your Internet connection is working." - "Die Konfiguration für Visum Publisher konnte nicht gefunden werden. Stellen sie sicher, dass die Internetverbindung funktioniert"
"Error while accessing Visum Publisher" - "Fehler beim Zugriff auf Visum Publisher"
Firewall or proxy-server settings of user's environment prevent Visum to connect to relevant URLs and thus to Visum Publisher.
If the error still appears, make sure that access and requests to the following hosts is granted via HTTPS:
In case exceptions are set per software/application (e.g. in firewall), it is important to know that there are also requests to the https URLs by a background tool (DataTransferTool.exe). Visum installs this tool per default to %LOCALAPPDATA%\Programs\PTV Vision\DataTransferTool.
In case the error is still appearing, it is recommended to ask the user's IT to check the protocol file or log file created from Visum or the Data Transfer Tool to gain more insights which requests are still blocked.
The Visum-protocol "Protocol.txt" can be found under %APPDATA%\PTV Vision\PTV Visum 20XX\Log.
The DataTransferTool log file can be found under %LOCALAPPDATA%\PTV Vision\DataTransferTool\Log. It is partitioned by day.
