I had similar problems with that bot recently (i.e. the python bot "certbot"), so I looked around and found a very nice alternative named PJAC[0]. I have now switched a bunch of my domains to use PJAC, and so far it works like a charm. Its only dependency is Java (version 8 or higher). Everything else is bundled in the downloaded artifact, just as it should be.
