Cannot Browse or Connect to All of My Website

aaP_marvin26camarillo

Yesterday, I upgraded to a latest version of Nginx web server. I can connect to all of my website.
But right now, I cannot connect to all of my website. I can still access to aaPanel. I disabled aaPanel security firewall but the problem still persist.

Does the problem have relation to newly upgraded latest version of Nginx web server.?

Also, is this error log can help solve this problem?

I also got Nginx error log

Also I noticed, I cannot access my phpmyadmin website anymore.

Hello, please check if php8.0 is started? Is it normal after trying to restart php?

aaP_marvin26camarillo

php8.0 is currently started and restarted. I used php8.0 to all of my website. I used php7.4 for phpmyadmin website.
Still I cannot browsed all of my website and phpmyadmin website.

Hi, can you give us your aapanel information? The server makes a snapshot backup first, if possible, please send it to kern@aapanel.com.
It is recommended to fill in the following
Post link:
SSH IP address, account password and port:
aapanel login link address and account password:
Detailed problem description:

No post link will not be able to know which user's information is, and the problem will not be processed

I finally solved the problem. It seems there is a problem between aaPanel Security firewall and Ubuntu OS system firewall.
I used SSH secure shell access and use this command below to reset firewall setting

iptables -F
iptables -X
iptables -Z

panelPort=7800
sshPort=22

firewall-cmd --set-default-zone=public >/dev/null 2>&1
firewall-cmd --permanent --zone=public --add-port=20/tcp >/dev/null 2>&1
firewall-cmd --permanent --zone=public --add-port=21/tcp >/dev/null 2>&1
firewall-cmd --permanent --zone=public --add-port=80/tcp >/dev/null 2>&1
firewall-cmd --permanent --zone=public --add-port=${panelPort}/tcp >/dev/null 2>&1
firewall-cmd --permanent --zone=public --add-port=${sshPort}/tcp >/dev/null 2>&1
firewall-cmd --permanent --zone=public --add-port=39000-40000/tcp >/dev/null 2>&1
systemctl start firewalld

Please take note I did not reload or use this command firewall-cmd --reload
