Hey @franciscojnneto. I have implemented a fix that will solve this SSL issue. Now, when you utilize the IGNORE_SSL_ERRORS=True definition, the library will properly ignore the SSL errors and initialize the API connection. This causes the library to A) suppress the SSL verification warning messages, and B) allow the API transaction to be successful. If you ever require more verbosity, you can also use the --verbose flag which will show you the raised exception. Note: the --verbose flag is new and will be further implemented throughout the library when possible
