ScaleFT relies on LetsEncrypt to provision TLS certificates for custom domains associated with Access Fabric applications. In response to a vulnerability report LetsEncrypt has disabled the TLS SNI challenge type, which ScaleFT currently relies upon. This is preventing ScaleFT from obtaining new certificates for custom domains.
This issue does not affect Server Access users.
We expect this issue to be resolved before any existing certificates expire, so Access Fabric applications which already have custom domains associated should also be unaffected.
