.net 6 mssql A connection was successfully established with the server, but then an error occurred

A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 31 - Encryption(ssl/tls) handshake failed)

I think I've solved it, the solution is to downgra：

Modify the openssl.conf file：
//under oid_section = new_oids
openssl_conf = default_conf
//End-of-file append

[default_conf]
ssl_conf = ssl_sect
[ssl_sect]
system_default = system_default_sect
[system_default_sect]
MinProtocol = TLSv1
CipherString = DEFAULT@SECLEVEL=1
save and qiut.
2. Take immediate action

source /etc/profile
