на моем сервере Debian 11 Bullseye 5.10.0-20-amd64
# nginx -V
nginx version: nginx/1.18.0
built with OpenSSL 1.1.1n 15 Mar 2022
TLS SNI support enabled
при использовании конфигурации SSL от mozilla (https://ssl-config.mozilla.org/#server=nginx&version=1.18.0&config=intermediate&openssl=1.1.1n&guideline=5.6), nginx применяет только TLS 1.3. Я не могу подключиться с TLS 1.2 к серверу.
* [CONN-0-0][CF-SSL] TLSv1.0 (OUT), TLS header, Certificate Status (22):
* [CONN-0-0][CF-SSL] TLSv1.2 (OUT), TLS handshake, Client hello (1):
* [CONN-0-0][CF-SSL] TLSv1.2 (IN), TLS header, Unknown (21):
* [CONN-0-0][CF-SSL] TLSv1.2 (IN), TLS alert, protocol version (582):
* OpenSSL/3.0.7: error:0A00042E:SSL routines::tlsv1 alert protocol version
* Closing connection 0
curl: (35) OpenSSL/3.0.7: error:0A00042E:SSL routines::tlsv1 alert protocol version
Некоторые клиенты используют службы на моем сервере, которые не поддерживают TLS 1.3. Все они не могут подключиться на данный момент.
Кто-нибудь знает, почему этот f * nginx применяет только TLS 1.3?
В конфиге nginx нет строки (просматривал nginx -T), в которой написано только TLS 1.3. Я совершенно не понимаю, как это исправить, поэтому любая помощь или указания, где искать, очень ценятся.

Я мог бы решить проблему, собрав nginx из исходников. Без изменений конфигурации теперь работает. Я не знаю почему, но nginx по умолчанию из репозиториев Debian отказывается использовать TLS 1.2 на моей машине.
