The host you requested is unknown or cannot be found

AI generated answer (using internal Slack threads):

The error message "The host you requested is unknown or cannot be found" typically indicates that the host you are trying to connect to is either not available or does not exist. This could be due to a number of reasons such as the host being down, the host name being incorrect, or network issues preventing a successful connection. In the context of NetSuite, if you are trying to connect to a Suitelet app and are receiving a "server did not respond" error, it could be due to similar reasons. The host key for the Suitelet app might be incorrect or the app itself might not be running. One way to retrieve the host key of an external SFTP server in NetSuite is outlined in the NetSuite Help Center. You can access this information by navigating to the following URL: Retrieving the Host Key of an External SFTP Server If you are still facing issues, it might be helpful to check the page source of the Suitelet app. The last few lines of the page source often contain useful information, including the host that the instance is running on. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
