@pravekal,

The prerequisite checks make sure that your ECE installation can operate as expected after the installation is complete. If the prerequisites aren't met, the ECE installation will not proceed.

In this case, it looks like you might not have met some of the required prerequisites around networking? The networking prerequisites are listed in [https://www.elastic.co/guide/en/cloud-enterprise/current/ece-prereqs.html#ece-prereqs-networking](https://www.elastic.co/guide/en/cloud-enterprise/current/ece-prereqs.html#ece-prereqs-networking). I would make sure that your host machines are configured correctly and then try installing again.

Hope this helps,

Nik
