And by some reasons, there is no SQL support.

SSL Error for this driver does not really mean it's SSL ERROR, in most cases it could mean, that connection can't be established, from the first step. Check if port really available, you could try it by using some different tools, like DBeaver.

And unfortunately I can't recommend this driver you trying to use, it's unstable. May throw sigfault errors randomly and have other bugs. I would recommend using this driver instead, in most scenarios both are compatible, this one just more stable and predictible. And this driver used by lots of other Python projects, like SQLAlchemy, Django, irissqlcli, and more based on them.
