Difficulty Accessing Server

[CGOODDAY]

Hi guys.
I observed that sometimes, fusion pbx suddenly becomes inaccessible for some time. Even when you restart your server, it will just give you access to it for some few minutes and after then, it starts becoming difficult again and may not give you access to itself until possibly a restart again and it continues same way.
What am I not doing right.
Thanks

Check the logs in the usual places:

Journal: # journalctl
Website:
# cat /var/log/nginx/access.log
# cat /var/log/nginx/error.log
# cat /var/log/php7.4-fpm.log
