Have you used the right certificate ( format ) and uploaded the same ?
Can you share the screenshots of the issue ?

2022-03-21T07:46:33.697+00:00 Hi Girish,
yes, still issue persists. We are actually passing to value to the program for validation. One is the Federation Metadata XML(refer the below) and the Base64 encoded response. Our response is Assertion signed. X.509 certificate present in Federation metadata xml and in response which used for sign the asserstion should match, but is different. Hence we are getting error "signature not valid, signature cryptographic validation not successful".
Both the certificate should match in order to validate the source. Please help us in which scenario, Azure is sending the different certificate which is not in federation metadata.
