I found the fix
flanker/flanker/addresslib/address.py line 322

from
plugin = plugin_for_esp(exchanger)

to
plugin = plugin_for_esp(exchanger.decode('utf-8'))

I'm having the same problem on Python 3.6. I'm surprised no one has commented on this ticket created back in June.

Feels like a dead project to me.

Hey guys!
This has actually been fixed, but the pypi package isn't up to date. Anyone know who we should contact?

skip_remote_checks = True is a workaround ... as long as you guys don't need more stringent validation for production. I'd like to have it, so I'm awaiting.

Python 3.9 and Flanker v0.9.14 and issue does still exist.
Idk why the PR was never merged in :(
