DNS exception means that the Domain Name System (DNS) has a problem when resolving the domain name, so it cannot convert the domain name into an IP address.

Common reasons are:

1. Network Connection issues: When your device can't communicate with the internet, the DNS server can't return you the correct IP address.

2. DNS server failure: If the DNS server you use fails, the domain name cannot be successfully resolved. DNS server failures can occur locally, at your ISP, or globally.

3. DNS cache: If you have visited a website and stored its DNS information, you may not be able to obtain the new address of the website immediately. This is due to browsers and operating systems storing DNS information in local caches to speed up access.

Solution:

1. Check network connection: Make sure your device is connected to the Internet. If you are using a Wi-Fi connection, try connecting to another available Wi-Fi network, or use a network cable to connect your computer directly to the router.

2. Modify DNS server: You can change the DNS server used by your device and set it to the server of an alternative DNS service provider such as Google DNS or OpenDNS. This can help you resolve DNS anomalies by using different DNS resolution.

3. Clear DNS cache: Clearing DNS cache helps remove old and erroneous DNS information stored on the local computer. Open a command prompt or terminal window and type the "ipconfig /flushdns" (Windows) or "sudo killall -HUP mDNSResponder" (Mac) command to clear the DNS cache.
