Hi, Generally the error “Unable to establish connection . Check the host and client number is correct and client and server belong to same Denodo major version” occurs when the Version of Denodo Platform and the version of the driver used to connect to, does not match. In that case, I would check if I have the correct driver version in place to connect to the required Denodo Platform. You can download the compatible driver from the [JDBC](https://community.denodo.com/drivers/jdbc/7.0) section of the DRIVERS document and test the connection to Denodo Coronavirus Data Portal. Furthermore, for more information on the Coronavirus Data Portal, you could take a look at the [Coronavirus Data Portal](https://www.denodo.com/en/page/coronavirus-data-portal) page of the Denodo Corporate website Hope this helps!
