EC2 - ERR_CONNECTION_TIMED_OUT

Question

I have a ec2 free tier instance running linux, apache web server and nodejs app.

I have configured security group and it worked ok so far.

But now i can not access server through DOMAIN or IP with port (port have opened in inbound rule).

I use ssh to remote server and log pm2 but it work ok. Then I have using lynx to browser localhost in command and nodejs app still running in that port.

Apache log is active (running).

Before I write this post, I cannot connect ssh to server and instance have status StatusCheckFailed_Instance, and I reboot instance, so it worked ok. After that, about 2 hour, I access again and met this problem.

Can anyone suggest what make this problem. Thanks.

UPDATE

After reboot ec2 instance, it works ok, but after 10 minutes cannot connect to server.

I go to log of apache in error_log.

At 17:32 I access ip ok. After 10 minutes it down. But in log file it error even in 17:32.

This is my apache config.

<VirtualHost *:80>    
     ServerAdmin **@gmail.com    
     DocumentRoot /var/www/html/hhs_api    
     ServerName api.***.xyz    
     Redirect / https://api.***.xyz/
    <Directory "/var/www/html/hhs_api">
         Order deny,allow
         Allow from all
         AllowOverride All
         Require all granted
   </Directory>    
<Location />
</Location>    
</VirtualHost>

This is ssl config

<VirtualHost _default_:443>
    SSLEngine On
    SSLProxyEngine On
    ProxyRequests Off
    ProxyPreserveHost On
    SSLProxyVerify none
    SSLProxyCheckPeerCN off

    SSLCertificateChainFile "/etc/httpd/conf/hhs_api-ssl/ca_bundle.crt"
    SSLCertificateKeyFile "/etc/httpd/conf/hhs_api-ssl/private.key"

        ProxyPass /  http://127.0.0.1:6969/
        ProxyPassReverse / http://127.0.0.1:6969/

    <Directory "/var/www/html/hhs_api">
         Order deny,allow
         Allow from all
         AllowOverride All
         Require all granted
   </Directory>
</VirtualHost>
