Expected Behavior
After renewal of certificate with external tools minio uses new version for http port without daemon restart. I expect the same behaviour for ftps.
Current Behavior
I need to restart daemon to make it reread new cert/key for ftps I see this bug since i started using minio late 2023
Steps to Reproduce (for bugs)
- launch minio with secure ftp and http configured
- put new certificate in files
- openssl s_client -connect minio_host:minio_https_port shows new cert
- openssl s_client -connect minio_host:minio_ftps_port shows old cert
- restart minio daemon
- openssl s_client -connect minio_host:minio_ftps_port shows new cert
