getting Error 521 host server down

Question

Hi
I have wordpress site on Lightsail. for security and speed I setup the cloudflare and now it gives ERROR 521 , almost everyday ( sometimes twice a day ) I need to restarted the server in order to have my site up and running.  I have to say that even before cloudflare, I used to get the server going down every few days !  it is running on Apache ( Bitnami) server. is there any way to extract the Error log file and pin point the issue ?
The SSL seems rightly setup and all the Cloudflare IPS are allowed ... I even stopped the Plugins and the problem did not go away !  I looked at metrics and seems hardly any resources are challenged. I had this site on another hosting company never had any issue with is , I wonder if lightsail is good enough .

Appreciate if anyone let me know if they encounter similar issues ,  or how to get the log file and see the errors.

Regards

Cyrus

Hello.

In the case of Bitnami WordPress, error logs are output to the following directory, so please check this directory.  
```
/opt/bitnami/apache2/logs
```

Logs located in the /var/log/ directory may also be helpful for troubleshooting.  
If you want to check the /var/log/ directory, you can do so by connecting via SSH.
