Unable to use TLSv1.1 or DHE-RSA-AES256-SHA?

Hello,

When trying to connect MariaDB 10.2.11 (hosted in Amazon RDS) instance using SSL I get an error "SSL connection error: unknown error number". Mysql console client connects well over SSL.

However other connections I have with MariaDB 10.0.24 work fine.

Using Mysql console I see following differences:

MariaDB 10.2.11

• Ssl_version: TLSv1.1
• Ssl_cipher: DHE-RSA-AES256-SHA

MariaDB 10.0.24

• Ssl_version: TLSv1
• Ssl_cipher: AES256-SHA

HeidiSQL output for the invalid connection:

/* Connecting to *obfuscated*.rds.amazonaws.com via MariaDB (TCP/IP), username masteruser, using password: Yes ... */
/* SSL parameters successfully set. */
/* SSL connection error: unknown error number */

I'm using HeidiSQL 9.5.05196 (latest) and have already tried re-installing HeidiSQL altogether.

Might new TLS or cipher version be to blame?

Please install the latest nightly built installer from the download page, so you get updated libraries as well as a newer heidisql.exe. I have added libmariadb.dll after the v9.5 release. It might solve your issue. If not, please create a ticket on Github.

Hi,

Latest nightly version worked like a charm! :)

Thanks!
