CyberPanel “This site can’t be reached” error message can occur for a number of causes, such as network problems, server outages, or incorrect setups. In this article, we’ll see the error troubleshooting details. At Bobcares, with our CyberPanel Support, we can handle your issues.
Overview
Why “This site can’t be reached” Occur in CyberPanel?
The “This site can’t be reached” error in CyberPanel can occur for several reasons, often related to network, server configuration, or domain settings. Here, we’ll see some of the common causes and how to fix them:
Common Causes
1. The server could be undergoing maintenance or be temporarily unavailable.
2. It is possible that firewall limits are preventing access to the required ports (such as 8090 for CyberPanel).
3. The IP address or URL that we use can be out-of-date or wrong.
4. There can be problems with the device’s and the server’s network connectivity.
5. There may be a problem with the CyberPanel service (lscpd).
6. It’s possible that a full disk on the server is keeping services from working properly.
7. The firewall settings on the server could have banned or not whitelisted the IP address.
8. SSL certificate issues may make connections insecure.
9. The server doesn’t correctly points to by DNS records.
Available Fixes
1. We can use tools such as traceroute or ping to check the server status. We may have to wait for the server to restart or get in touch with the hosting company if it is unavailable.
2. Make sure that the firewall permits traffic on the necessary ports. Commands such as these are available:
sudo systemctl stop firewalld firewall-cmd --add-service=http firewall-cmd --add-service=https firewall-cmd --zone=public --add-port=8090/tcp
After making changes, restart the firewall.
3. Make sure the URL goes to the proper server by double-checking it for mistakes. We can use Dig or nslookup in order to confirm DNS settings.
4. Check the internet connection and try using a different network or device to see the website. If it continues, get in touch with the ISP.
5. 5. Use the below code to restart the service.
sudo service lscpd restart
6. Use this to check disk usage:
df -h
Use the following commands to find huge files if the disk is full:
du -hsx /* | sort -rh | head -10
To make space, remove files that aren’t necessary.
7. Whitelist the IP address if we’re using CSF (ConfigServer Security & Firewall):
csf -a YOUR_PUBLIC_IP
8. Verify that the certificates setup are correct and are valid by checking the SSL configuration.
9. Check DNS settings by using command:
dig domain.com NS
Check that the nameservers are propagated and configured appropriately.
