The additional read may read the TLS shutdown alert from the wire. The TLS record layer can send additional messages besides application layer data, e.g. for post handshake authentication, sessions, rekeying, and to indicate that one side is shutting down the current TLS connection. To investigate you can either use the undocumented SSLContext._msg_callback debug hook or Wireshark with SSLKEYLOGFILE env var (available since 3.8). ---------- nosy: +christian.heimes _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36098> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
