 ## Updating known hosts
 
 The first time you interact with {% data variables.product.prodname_dotcom %} after switching to port 443, you may get a warning message
 that the host wasn't found in `known_hosts`, or that it was found by another name.

 It is safe to answer "yes" to this question, assuming that the SSH fingerprint matches
