# How to configure a NovaSeq 6000, with Control Software 1.8.x or greater, to work with a Proxy Server

After upgrading NovaSeq 6000 Control Software (NVCS) from version 1.7.5 or older, users may experience issues with utilizing the proxy server. Use this article to make the necessary configuration changes to continue utilizing the proxy server successfully. If the NovaSeq 6000 is configured to use a proxy server on NVCS 1.8+ without these changes, it is possible to experience the following error shortly after run start: "*A component failed during sequencing and the run cannot be completed*."
