These warnings are generated because the version of
/opt/bitnami/common/lib/libssl.so.1.0.0 that is curl is using is different from the one the system is using. This is something that can happen on servers in which the library has been updated but the library that uses the Magento stack has not. However, the libssl warning is only a warning and should not break the curl command. Could you run the following command and paste the output?
