To help out, we’ve decided to make a guide for fixing the RADS error on League of Legends. 

Let’s get started!

2. Close Unnecessary Applications.

3. Check League of Legends Servers. 

The RADS error on League of Legends could also indicate a problem with the servers. If you still can’t connect to the servers, you can try checking the status of Riot’s servers to see if there is ongoing maintenance. 

Luckily, League of Legends has a dedicated status page so that players can easily check if there are issues with the platform.

Unfortunately, server-related issues can’t be resolved on your end. If the servers are down, the best thing you can do is wait. On the other hand, you can head to the next method if there’s no problem with the servers. 

4. Check Your Network Connection. 

A slow or unstable internet connection could also be the reason you encounter the RADS error on League of Legends. To confirm this, perform a speed test on your network using to measure your network’s upload and download bandwidth.

If the result indicates a problem with your network, restart your modem or router to re-establish the link with your ISP’s servers. 

Unplug your router’s power cable from the outlet and wait for 5 to 10 seconds before reconnecting it.
