    I got the same error from a flow: Error from token exchange: Bad Key authorization token. Token must be a valid JWT signed with HS256
    Failed to validate token: IDX10249: X509SecurityKey validation failed. The associated certificate has expired. ValidTo (UTC): '8/14/2024 11:59:59 PM', Current time (UTC): '8/26/2024 9:31:55 AM'.

    In my case, I solved the problem by doing the following:
     
    1. Create a new connection
    2. Delete the My Flow connection that is causing the problem
    3. Reset the newly created connection in 1 to my flow in 2.
     
    *Reset user password before step 1
    (Reset because the password has not been changed for a long time)
