Your device stores DNS information to help websites load faster. This is called the DNS cache.
Sometimes, this saved information can become outdated or incorrect. When that happens, your device may have trouble connecting to a website properly. A DNS flush clears this saved DNS information and allows your device to request fresh connection details.
You may want to flush DNS if:
The website is not loading correctly.
You recently changed networks or internet providers.
You are seeing connection or redirect errors.
The website works on another device but not on yours.
You have already restarted your browser, but the issue continues.
To flush DNS on Windows, open Command Prompt as administrator, enter the following command, and press Enter:
ipconfig /flushdns
To flush DNS on macOS, open Terminal, enter the following command, and press Enter:
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
You may be asked to enter your Mac password. The command may not show a confirmation message, but the DNS cache will be cleared.
On iPhone or Android, the easiest way to refresh DNS is to restart the device or turn Airplane Mode on and off.
If the issue continues, clear your browser cache and cookies. This can usually be done from your browser settings under Privacy or Clear browsing data. Select Cookies and Cached files, then clear the data.
Please note that clearing cookies may sign you out.
After completing these steps, restart your browser and try accessing the website again.
If the issue continues, try another browser, another internet connection, or contact Support with a screenshot of the error message.
