Problem Statement
If your internet connection appears active but websites won’t load, the issue is usually related to DNS resolution, browser configuration, or network-level connectivity problems.
This can happen even when your device shows a strong connection to Wi-Fi or Ethernet, because being connected to a network does not always mean your device can successfully reach websites.
This guide helps you identify where the failure is occurring so you can apply the correct fix and restore access quickly.
Common Symptoms
You may notice symptoms like:
• Your browser shows “This site can’t be reached.”
• Pages keep loading but never open.
• Some websites work while others fail to load.
• Error messages like DNS_PROBE_FINISHED_NXDOMAIN appear.
• Internet-connected apps work, but websites do not.
These symptoms usually indicate a problem with DNS resolution or network routing.
Identify Where the Failure Is Happening
Before troubleshooting further, try to determine where the failure occurs.
Websites Fail on All Devices
If no devices can open websites, the issue may involve:
• DNS server problems
• router configuration
• ISP connectivity issues
If you see a “DNS server not responding” error, follow this guide:
DNS Server Not Responding: Causes and Fixes
Websites Fail on One Device Only
If other devices work normally, the issue is likely:
• browser cache corruption
• firewall restrictions
• incorrect network configuration
In that case, see:

Step-by-Step Fixes
Step 1 — Check if the Website Is Down
Before changing anything, confirm the website is online.
Try:
• opening the site on another device
• switching to mobile data instead of Wi-Fi
If the site is down everywhere, the problem is on the website server.
Step 2 — Restart Your Network Connection
Temporary network issues can prevent DNS resolution.
Restart:
• your modem
• your router
• your computer or device
Wait until the router reconnects before testing again.
Step 3 — Clear Browser Cache
Browsers sometimes store corrupted or outdated files.
Clear:
• cache
• cookies
• stored site data
Then restart the browser.
Step 4 — Check DNS Issues
DNS (Domain Name System) translates website names into IP addresses.
If DNS fails, your browser cannot locate the website server.
Try:
• restarting your device
• flushing the DNS cache
• switching to a public DNS provider
Step 5 — Test a Different DNS Provider
Sometimes your ISP’s DNS server becomes unstable.
You can test alternative providers like:
8.8.8.8
8.8.4.4
1.1.1.1
1.0.0.1
When the Issue Is Not on Your Side
Sometimes the problem occurs outside your local network.
Possible causes include:
• DNS server outages
• hosting server problems
• domain configuration errors
If the problem persists across devices and networks, the website itself may be experiencing an outage.

Final Tip
If your internet connection appears active but websites still refuse to load, start by identifying whether the issue is caused by DNS resolution, browser configuration, or a network outage.
Working through the steps above will usually identify the root cause quickly.
