This won't work. You need to sign the message (see format in OP) using the address
you invested with. In this case you invested with Address A (1569sNNM8G6jhAqiMaoReEnfc146q3LAQj) and signed with Address B (1FLLVFpdnBQLULcQvYLUqKHiqvfKEjFCDx). You need to sign a message with
Address A.
this is from my exchange wallet, sorry could not figure how to sign
You can't. If you manage to properly sign the first address (as mentioned above), it will be fine.
