This issue occurs when the configured sysctl parameters are not part of the allowlist file.

NSX Manager supports system control APIs or sysctl keys to tune system control configuration parameters on an NSX Edge. In NSX for vSphere 6.2.0, these APIs are documented in an allowlist file and validated by the Edge. Other sysctl keys that are not documented in the allowlist are not validated and considered as invalid and NSX Edge upgrade to 6.2.0 or later fails.
