MySQL ERROR 2026 – SSL connection error – Ubuntu 20.04

Ubuntu 20 has improved the security level.
The only way i could connect was allowing the tls 1 .

Edit this file:

/usr/lib/ssl/openssl.cnf

And put at the beginning of file:

openssl_conf = default_conf

And in the end of that file too:

[ default_conf ]

ssl_conf = ssl_sect

[ssl_sect]

system_default = ssl_default_sect

[ssl_default_sect]
MinProtocol = TLSv1
CipherString = DEFAULT:@SECLEVEL=1

It help me a lot: https://askubuntu.com/questions/1233186/ubuntu-20-04-how-to-set-lower-ssl-security-level
