When expanding more details below the error can be seen:

"An error occurred trying to authenticate the user."

More Details
System.DirectoryServices.DirectoryServicesCOMException (0x80072020): An operations error occurred. at System.DirectoryServices.PropertyValueCollection.PopulateList() at System.DirectoryServices.PropertyValueCollection..ctor(DirectoryEntry entry, String propertyName) at System.DirectoryServices.PropertyCollection.get_Item(String propertyName) at System.DirectoryServices.AccountManagement.PrincipalContext.DoLDAPDirectoryInitNoContainer() at System.DirectoryServices.AccountManagement.PrincipalContext.DoDomainInit() at System.DirectoryServices.AccountManagement.PrincipalContext.Initialize() at System.DirectoryServices.AccountManagement.PrincipalContext.get_QueryCtx() at System.DirectoryServices.AccountManagement.Principal.FindByIdentityWithTypeHelper(PrincipalContext context, Type principalType, Nullable`1 identityType, String identityValue, DateTime refDate) at System.DirectoryServices.AccountManagement.Principal.FindByIdentityWithType(PrincipalContex)

 

Resolution

When looking at the IIS authentication for the K2 Designer site, it is observed that the Windows authentication is disabled. When reading the error it seems that Windows authentication is attempted but not allowed.

Enabling the Windows authentication in the authentication of the K2 Designer site in IIS resolves this issue.
