Hi The application was working ok with PyOpenSSL 18.0.0 version so far, however we suddenly went into an issue as module lib has no attribute X509_V_FLAG_GB_ISSUER_CHECK

Did you upgrade the version of pyca/cryptography you use? If so, did you read the changelog? https://cryptography.io/en/latest/changelog/#v38-0-0
Removed several legacy symbols from our OpenSSL bindings. Users of pyOpenSSL versions older than 22.0 will need to upgrade.
