Error : The request was aborted: Could not create SSL/TLS secure channel. Inner exception :

    Can you try upgrading your system CA?

    This issue is because of an old root CA certificate expired on May 30th that affects old systems that are not updated with new root CA certificates. More about it: https://support.sectigo.com/Com_KnowledgeDetailPage?Id=kA03l00000117LT . Ideally all systems should be up to date with updated CA certificates.

    Sujith thanks for pointing out the issue but the issue is coming randomly. Sometimes it connects OK and place trades sometimes it gives error. if there is certificate issue it should not connect at all from particular system. Please suggest.

    Sujith, can you please update on this? This is very strange behavior. Sometimes trade takes place from same machine and sometimes it throws "Could not create SSL/TLS secure channel" error.

    Can you give us a complete stack trace?
    It is not possible to check anything with this one line.
    We have replaced all the certificates. It shouldn't be happening anymore.
