what kind of message are you trying to verify?

Maybe you can verify it manually with sage and follow the Signtaure verification Algorimth

You may have misunderstood what that tool is doing.
It verifies if a message was correctly signed from a certain address.
However, I took my staked address from here: https://bitcointalk.org/index.php?topic=996318.msg53182208#msg53182208
And verified it:

You cannot verify signatures with Bitcoin transactions from these sites as they are made to verify signed messages instead. Signed messages has a different format as compared to transaction signatures; having "Bitcoin Signed Message:" added before the actual message, etc. I'm not sure what you're trying to achieve here. Are you trying to verify if a transaction has been signed correctly?

Yes. Because sites what provide info about r,s,z info information hard understand and get exat wrigh info. ASN.1 parsers for exmple cant get r,s from signature but 2xcoin.com can and vice versa...
