Signature cryptographic validation not successful - opensaml

Question

I am a newbie to SAML and inherited an application with spring boot and SAML extension. I have problem to update the certificate in test environment. The certificate in production was updated without issue earlier. The certificate is packaged in the war file. Here are the last part of the log outputs.
