In OpenSSL 3.5.0, the "quic_transport_parameters" extension set internally by the QUIC API is cleared on the SSL context switch, which disables sending QUIC transport parameters if switching to a different server block on SNI. See the initial report in [1]. This is fixed post OpenSSL 3.5.0 [2]. The fix is anticipated in OpenSSL 3.5.1, which has not been released yet. When building with OpenSSL 3.5, OpenSSL compat layer is now used by default. The OpenSSL 3.5 QUIC API support can be switched back using --with-cc-opt='-DNGX_QUIC_OPENSSL_API=1'.
