Hi, Here is a similar question you can refer to [link](https://community.denodo.com/answers/question/details?questionId=9060g000000XessAAC&title=Unable+to+connect+to+VDP+-+User+Name+and+Password). As explained, for fresh installation of Denodo Express the default username is admin and password is admin, if you still cannot log in using the default admin/admin, even after a clean reinstallation, you may need to check the following: * Ensure that Virtual Dataport Server is started. * Check if the port number “9999” is not used by another application because this will block the Virtual DataPort Server from being started up. * Check if any firewall is blocking the ports when you access the Virtual DataPort server. * Ensure that you are running the Denodo Platform as an administrator. * If you are using multiple network interfaces, ensure that you have specified the correct IP address or hostname in the “Denodo Control Center>Configure>JVM options>RMI Host>Virtual DataPort Server”. Hope this helps!
