Emojis are not valid in domain names… Really this is pyopenssl’s fault, it should squash the error since it isn’t relevant (invalid subjectAltName that doesn’t match the domain we’re fetching anyway).

They’re correct. This is firmly in urllib3 in it’s urllib3.contrib.pyopenssl module that uses pyOpenSSL. That’s clear in the stack trace.
