Network errors:
Some Java environments start with IPv6 Stack. If this happens, while actually running IPv4 the result might be network errors. In order to prevent errors, the Servoy Application server can be started with a preference to use the IPv4 Stack.

• Open servoy_server.sh/servoy_server.bat in the <servoy>/application_server/ directory using a text editor
• Add '-Djava.net.preferIPv4Stack=true' to the end of the line that starts with 'java'
• Save the change made

• \[Re]start the Servoy Application Server
