Issue Summary
We are trying to connect to the MySQL Instance from Redash with SSL connection;
however, it is failed with error message “Protocol Version Mismatch”.
Both OS and Redash are old version, so it might be TLS related issue; however, if you know any solution or workaround, please give me advice.
- Configuration (Pem is generated by MySQL8.0)
- Error Message
OS is using OpenSSL 1.0.1f 6 Jan 2014
MySQL8.0 is allowed connection from TLS1.2.
PS:
I downloaded mysqlsh then I tested MySQL connection from the redash server.
It is working fine with “–ssl-ca=” option. So pem, connection and account is OK.

Technical details:
- Redash Version: redash.4.0.1.b4038
- Browser/OS: Ubuntu 14.04.5 LTS
- How did you install Redash: Unknown (It is installed by ex-employee)
