The Application log logs:
Exception when creating CryptoServiceProvider: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms. Local Security Policy -> Security Options -> System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing - should be disabled
And a .Net Runtime error:
Exception Info: System.InvalidOperationsException at System.Security.Cryptography.MD5CryptoServiceProvider..ctor() at QDSMain.Clustering.DefaultClusterNotification.Work.Thread() ...
QlikView 12.10 and alter versions
The issue is a result of a Code change from FileWriteTime to an MD5 Hash for the notification files related to the QDS services. If FIPS is enabled, it may result in the error. This is considered to be working as designed.
