from 29/12/2021 on my TDR I get this message:
Trouble (Failed to configure malicious md5 list Downloaded MD5 list failed MD5 check FailureCode = 43)
Some idea ?
or a few minutes ago the problem disappeared by itself
It sounds like the system may have been in the process of generating a new definition for the system.
Should something like this occur, TDR will continue to run with it's current MD5 exception list, so there's no need to worry about this unless this has gone on for some time.
