There is a template for reporting bugs. I can’t help you with the information you’ve provided.

Regarding usage of the client and server programs, have a look at the examples in test_tls.py. The tests were flaky under windows in the CI, though. Since I don’t have a windows machine available, I wasn’t able to look further into it.

Closing because reporting an issue with only a stack trace isn’t serious.
