Hello all,
I currently use the following parameters to achieve exactly the same objective:
sslVersionMin = TLSv1.2
sslVersionMax = TLSv1.3
In fact, here is my full tls.conf file:
; TLS Configuration file
sslVersionMin = TLSv1.2
sslVersionMax = TLSv1.3
ciphersuites = TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_256_GCM_SHA384
ciphers = ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384
curves = X25519:P-256:X448:P-521:P-384
options = NO_COMPRESSION
options = NO_TICKET
Nothing fancy, and it works as expected. Maybe you are overriding your parameters somewhere else ?
Best regards,

Howdy,
; Use sslVersionMax or sslVersionMin option instead of disabling specific TLS protocol versions when compiled
; with OpenSSL 1.1.0 or later.
sslVersionMin = TLSv1.2
Produced no efect, openssl is 1.1.1g
any idea?

P.S.
There's also an sslVersionMax if you feel you need it.

Thanks in advanced,
sslVersion = all
