We’re aware of an issue where players sometimes receive the message “An error has occurred. Please try again later.” when attempting to claim event rewards. This can be resolved by clearing your DNS Cache.

If you’re uncertain about how to do this, you’ll find instructions below.

How to Clear DNS

DNS (Domain Name Server) is what "matches" your everyday links to the internet with an actual IP address.

Your system will automatically collect and store IP addresses and other DNS results to speed up subsequent requests it makes to the same hostname. This is perfectly normal, but at times bad or corrupted results may be stored, and they need to be cleared from your cache to communicate with hosts correctly. Likewise, your TCP/IP settings may get corrupted and need resetting.

To clear your DNS cache and reset your TCP/IP settings, please follow these steps:

  1. From Windows Start, search for "cmd".
  2. Right-click on Command Prompt and click Run as Administrator.
  3. In the console, type the following command:ipconfig /flushdns
  4. If the command was successful, you will see the message "Successfully flushed the DNS Resolver Cache."
  5. Afterwards, type:netsh int ip reset
  6. Once done, restart your computer as prompted.

This should not only fix the issue but will generally make your connection feel smoother and more responsive.

If the above doesn't help, you can try using an alternate DNS server. In the worst-case scenario, when using a bad DNS, the requests you make to a domain will not be answered because they’re unable to reach their destination.

To make sure this does not happen, please change your DNS to one of the three suggested below:

  • Google Public DNS (aka
  • Cloudflare DNS (aka
  • Quad 9 DNS (aka

Here’s how to do it.

  1. Go to the Control Panel / Settings.
  2. Click Network and Internet > Network and Sharing Center > Change Adapter Settings.
  3. Select the connection for which you want to configure the DNS. For example:
    1. To change the settings for an Ethernet connection, right-click Local Area Connection > Properties.
    2. To change the settings for a wireless connection, right-click Wireless Network Connection > Properties.
  4. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  5. Select the Networking tab.
  6. Under This connection uses the following items, select Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6).
  7. Click Properties.
  8. Click Advanced and select the DNS tab.
  9. If there are any DNS server IP addresses listed there, note them down for future reference (in case you need them again later), and remove them from this window.
  10. Click OK.
  11. Select Use the following DNS server addresses.
  12. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.
  13. Replace those addresses with the IP addresses of the DNS servers you want to use:
    1. (Google Public) For IPv4: and
    2. (Cloudflare) For IPv4:
    3. (Quad 9) For IPv4:
  14. Restart the connection you selected in step 3.
