Azure Troubleshoot mTLS provides a helpful guide on ensuring formatting and validation steps. To make this more tailored, are you trying to: Generate a new one for a custom project? Extract an existing one from Kubernetes? Download one from a cloud provider (like Azure/AWS)?
: On your servers, ensure the clientca.pem file is readable by the service user (e.g., www-data for Apache) but not writable by other processes.
