Bug report

Bug description:

@freakboy3742: The buildbot has failed test_preauth_data_to_tls_server in 3 out of the last 5 runs on the main branch:

AssertionError: 'before TLS handshake with data' not found in '[SSL: RECORD_LAYER_FAILURE] record layer failure (_ssl.c:1109)'

There are also a lot of other SSL warnings and errors in the logs, but I don't know if they're related.
