Do I have to configure firewall or proxy settings?

To use visTABLE® all the following ports and URLs must be enabled in your firewall / proxy: 

• required: 
TCP/IP Port 80 (HTTP), 443 (HTTPS) - outgoing
URLs: cloud.vistable.de, registerserver.net, 
https://vistable.table.core.windows.net , https://plavis.azure-api.net,  
https://dev--sh6v1tb.auth0.com , https://dev--sh6v1tb.eu.auth0.com 

• 3D-View: 
TCP/IP ports ranging from 1024 to 65000 (at least port 9120) on localhost 

• Optional for Logs: 
TCP/IP Port 443 - outgoing
URLs: dc.applicationinsights.azure.com, dc.applicationinsights.microsoft.com, 
dc.services.visualstudio.com 

Make sure that you run visTABLE® once after installation and create a layout. Corresponding requests from the Windows firewall are to be answered with "Allow". This creates a default rule in the Windows Firewall. A user needs elevated privileges to create such a rule.
