Hi, For the “Connection timed out” error, I recommend checking your firewall to ensure that the necessary ports are open. The default ports used by the Virtual DataPort server can be found [here](https://community.denodo.com/kb/view/document/Ports%20needed%20by%20the%20VDP%20Server?category=Operation). For a complete list of default ports, you can look at the [Default Ports Used by the Denodo Platform Modules](https://community.denodo.com/docs/html/browse/latest/platform/installation/appendix/default_ports_used_by_the_denodo_platform_modules/default_ports_used_by_the_denodo_platform_modules). For more information about this error, you can refer to a similar [Q&A question](https://community.denodo.com/answers/question/details?questionId=9060g000000XdQJAA0&title=Connection+error%3AConnection+timedout+connect). Hope this helps!
