What to Do If a Website Is Not Opening (DNS & Cache Troubleshooting) Print

If you are having trouble accessing a website or client area—while other websites seem to work fine—the issue is often caused by outdated local DNS records, cached browser data, or temporary network routing glitches.

Follow these step-by-step instructions to resolve the issue on your device.

Step 1: Flush Your Local DNS Cache

Your computer stores IP addresses of websites you visit to load them faster. If an IP address changes or gets temporarily blocked, flushing your DNS forces your system to fetch the fresh, updated location.

• Windows:

  1. Press Windows Key + R, type cmd, and press Enter.

  2. In the command prompt, type the following command and press Enter:

     Plaintext

      

     ipconfig /flushdns
     

  3. You should see a message confirming the DNS resolver cache was successfully flushed.

• macOS:

  1. Press Command + Spacebar to open Spotlight, type Terminal, and press Enter.

  2. Run the following command (you may be prompted for your Mac password):

     Plaintext

      

     sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
     

Step 2: Clear Your Web Browser Cache & Cookies

Browsers save files and cookies to speed up browsing, but corrupted or old cached data can cause loading errors.

1. Open your browser settings (or press Ctrl + Shift + Delete on Windows / Cmd + Shift + Delete on Mac).

2. Select Browsing Data or Clear Browsing Data.

3. Set the time range to All Time.

4. Check the boxes for Cookies and other site data and Cached images and files.

5. Click Clear Data and restart your browser.

Alternative Quick Test: Try opening the website in an Incognito / Private Window or using a different web browser.

Step 3: Restart Your Internet Modem / Router

Network routers maintain their own internal cache and dynamic IP tables. Restarting your equipment clears temporary routing table issues.

1. Unplug the power cable from your internet modem and router.

2. Wait 30 to 60 seconds.

3. Plug the power cable back in and wait until all status lights return to normal.

4. Try accessing the website again.

Step 4: Restart Your Computer

A simple system reboot clears temporary system memory errors and forces your network drivers to re-initialize clean connections.

1. Save your open work.

2. Restart your PC or Mac.

3. Try loading the website after the reboot.
