I have a AWS Lightsail Bitnami LAMP 7.4.27-16 machine that every night stops responding at random time. I installed LetsEncrypt certificate and vsftpd for a new specific ftp user.
On the machine all seems working properly. The server is listening, cpu is ok, ram is ok, I can connect to it by SSH. Apache and MariaDb services are running. Only the website load infinitely (http or https).
These are the last access_log lines:

What can I do now? There are some commands or logs to check?
