How To Flush Your DNS Cache

How to Flush Your DNS Cache

If you see an error in your PhotoBiz control panel that says, “An unexpected error occurred, please check your network connection and try again,” the issue is often related to cached DNS data on your computer.

Flushing your DNS cache clears stored website address records and forces your computer to request fresh information. This can resolve connectivity issues, loading problems, and outdated website data.

This guide explains when flushing DNS is helpful and how to do it on both Windows and macOS computers.

Why Flushing Your DNS Cache Helps

Your computer stores DNS (Domain Name System) records to quickly load websites you’ve previously visited. Sometimes those records become outdated or corrupted.

Flushing your DNS cache can help:

Resolve outdated or incorrect website data
Fix connectivity issues when websites won’t load
Correct errors after domain or server changes
Improve browsing performance
Clear potentially corrupted DNS records

This is especially helpful after:

Connecting to a new network
Updating domain settings
Migrating hosting or servers
Seeing unexpected network-related errors in your PhotoBiz account

Windows (Microsoft/PC Users)

Open Command Prompt

Press the Windows Key + R on your keyboard.

Type cmd in the Run box and press Enter.

This will open the Command Prompt window.

Enter The DNS Flush Command

In the Command Prompt window, type:

ipconfig/flushdns

Press Enter on your keyboard to flush your DNS cache.

FINAL STEP

Confirm Success

If the command runs successfully, you will see the message:

“Successfully flushed the DNS Resolver Cache.”

Once you see this message, your DNS cache has been cleared. You can now reopen your browser and log back into your PhotoBiz account to test again.

macOS (Apple users)

STEP ONE

Open Terminal

Press Command + Space to open Spotlight Search.

Type Terminal and press Enter.

The Terminal application will open.

STEP TWO

Enter The DNS Flush Command

For macOS Tahoe:

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

Press Enter.

You may be prompted to enter your computer’s administrator password. Type your password and press Enter again.

You will not see a confirmation message. This is normal.

FINAL STEP

Test Your Connection

After running the command, close Terminal.

Open your web browser and log back into your PhotoBiz account. Your computer will now request fresh DNS information from the network.

If the error was caused by outdated DNS records, it should now be resolved.

Additional Notes

You only need to flush DNS when troubleshooting connectivity issues.

Flushing DNS does not delete files, browser history, or saved passwords.

If issues continue after flushing DNS, restart your computer and router.
