Because the system automatically manages these files upon restart, manual fixes like static file replacement are often overwritten or rendered ineffective. Recommended Resolutions

Instead of relying on auto-generated system certificates, use a manually configured Public Key Infrastructure (PKI) to ensure certificates do not change unexpectedly on service restarts.

The issue is often triggered by how systemd services interact with automatically generated certificate files. When the service restarts, it may recreate or misconfigure the paths to these certificates, leading to a "handshake failure" or validation error.

The code is associated with a specific, long-standing bug in MySQL regarding secure remote connections. The Issue: SSL/TLS Connection Failures

Users often see errors indicating they "cannot connect to remote mysql-server" despite having correct credentials and network access.

Ensure that the ssl-ca , ssl-cert , and ssl-key variables in the MySQL configuration (e.g., my.cnf ) point to the correct, persistent certificate files.

To resolve this connectivity issue, administrators typically need to:

If the service is regenerating files, use a systemd override to specify exact execution environments that don't interfere with your SSL setup.
