Setting this parameter to FALSE will cause an unquantifiable percentage of cloud connections to fail. Note that session data relayed via our cloud service is encrypted end-to-end, so cannot be deciphered by RealVNC, nor anyone else. However, intermediate network hardware may mean this is not possible, so the cloud service automatically falls back to relaying session data this ensures cloud connections succeed. Where possible, the cloud service then negotiates peer-to-peer sessions between endpoints, so session data is transmitted directly between them this is likely to be more performant.
