Cannot browse aaPanel

aaP_marvin26camarillo

Recently, I reinstall Nginx web server. Then I restart aaPanel server. But after that I cannot browse aaPanel anymore. I tried to use putty shell or SSH access but I got an error saying "Network error: Connection timeout.'. I reboot my cloud server host where my aaPanel is installed. Luckily it connects using SSH access. I tried to use /etc/init.d/bt command and restart aaPanel. But still I cannot browse aaPanel in the internet.
Currently my nameserver is 8.8.8.8

I also have other question. Once I reinstalled an Nginx web server, I cannot browse all of my website anymore.

I tried to search in aaPanel forum if there is same problem with me but no record is found.

Do you know what are the problem? Can you also find error? Please help.

I resolved my problem myself.

Solution. I changed my Ubuntu DNS namesever. Then I used this command apt reinstall firewalld in Secure Shell Access.
Then used this:

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

What I noticed after I logged in in aaPanel is my appanel security firewall is disabled.

I think the method may be disable aaPanel security firewall.

iptables -F
iptables -X
iptables -Z

panelPort=7800
sshPort=22

Still not solved. After I enabled aaPanel firewall. I lose connection to aaPanel again.

I finally saw the problem. Then I saw that my ip address is listed in the firewall blaclist. I deleted my banned ip and put a record in the whitelist. Now I do not lost connection to aaPanel.
