1.7.1 & Python 3.8.5: AttributeError: 'SocksiPyConnectionS' object has no attribute '_check_hostname'

It looks like today, I have some problems with one httpS host:-( It worked fine yesterday, so not sure, what changed. Firefox can successfully connect to the httpS host via the same ssh/socks proxy. I can connect to other hosts via similar ssh/socks proxies.

sockshandler.py is not recommended, you may try another one, extproxy is based PySocks.
