Getting bad certificate although OpenSSL validates the crt file correctly [closed]

edit

We have been trying to connect a server and the handshake fails with Bad Certificate. We have validated using OpenSSL and pulled the full set of certificates. We were able to verify that the certificates were good using OpenSSL s_client, but when we try the same process on our device, it is failing. We were successful using the self signed certificates, but not the CA signed.
