Why is Plex So Slow

Slowness of Plex is usually caused by:

  • Low data bandwidth
  • Bad internet connection
  • Bugs on your device or browser
  • Corrupted installation files
  • Outdated software

How To Fix a Slow Plex?

Here are the best solutions for how to fix a slow Plex.

1. Restart your device. Restarting your device will often clear most problems. So take a moment to reboot your device to see if it resolves lagging problems with the Plex.

Roku: Press the Home button on your remote. Navigate to Settings > System > System Restart.

Fire Stick: On your home screen click on the Settings icon > My Fire TV > Restart.

Chromecast: Open Google Home app. Select your device. Tap the Gear icon > More settings > Reboot.

Windows 11: Click on the Start menu > Power button > Restart

App: Android or iOS device

2. Check your internet connection. The quickest way to do this is to open another app or website that needs an internet connection.

If Wi-Fi is slow or down, switch to cellular. If cellular is slow or down, switch to Wi-Fi. The process of switching between Wi-Fi and Cellular connection depends on your platform: Android, or iPhone.

You can also toggle Airplane Mode on and off (AndroidiPhone)

Tip: Use a wired Ethernet connection if possible. This will provide a faster and more stable connection than Wi-Fi

3. Check if Plex’s down. The Plex service could be experiencing a server outage or other technical issues. If Plex is experiencing downtime, you’ll just have to wait for Plex to resolve the issue. 

4. Watch a different show. If you’re only having problems with one particular show, it’s possible that the problem is with the show itself. Try watching a different show to see if the problem persists.

5. Log out of Plex and log back in again. Quickly sign out and then back in to refresh the app and potentially fix any glitches affecting your Plex account.

Tip: If you suspect a stranger is accessing your Plex account, change your password to prevent them from logging in.

6. Disable VPN or proxy servers: If you are using a VPN or proxy server, try disabling it. Some VPNs and proxy servers can interfere with streaming apps.

Windows 11: Open Settings (Windows key + I), go to Network & Internet, and select VPN.

App:  Android or iPhone

7. Clear Browser Cache and Cookies: Clearing your browser’s cache and cookies can remove temporary files that may be causing performance issues with Plex.

Clear cache quickly via Ctrl+Shift+Del (Windows) or Command+Shift+Delete (Mac). Otherwise, try your browser’s Settings, Privacy, or Advanced options.

Tip: You can perform a hard reload of Plex to bypass the browser’s cache and force it to download the latest version of the pages. To do this, hold down the Shift key and press F5 (Windows) or Command + Shift + R (Mac).

8. Disable extensions or add-ons: Temporarily disable any browser extensions or add-ons, especially those related to social media or privacy, and check if Plex performance improves. If the slowness disappears, re-enable extensions one by one to identify the culprit.

On Google Chrome: Click the three dots in the top right corner >  More tools > Extensions

On Firefox: Click the three lines in the top right corner > Add-ons > Extensions

On Safari: Click Safari in the top menu bar, then select Preferences > Extensions

Tip: Open Plex in incognito mode to eliminate any interference from browser extensions or cookies. If Plex performs faster in incognito mode, it suggests an extension or cookie is causing the slowness.

9. Update Browser Version: Ensure you are using the latest version of your web browser. Outdated browsers may have compatibility issues with Plex, leading to performance problems. Download and install the latest updates for your browser from its official website.

On Google Chrome: Click the three dots in the top right corner, then select Help > About Google Chrome.

On Firefox: Click the three lines in the top right corner, then select Help > About Firefox.

On Safari: Click Safari in the top menu bar, then select Preferences > General > check the box next to Automatically check for updates.

Tip: Simply close any Plex tabs that you’re not using. The more tabs you have open, the slower Plex will be.

10. Try Plex on a different device or browser. If you are still having problems with slow Plex, try using a different device or browser to stream.

11. Check for Plex app updates. If you are using the Plex app on your mobile device, check for and install any Plex app updates on your Android device or app updates on your iPhone.

Tip: You can also try updating the streaming device’s firmware to the latest version.

12. Clear the Plex app cache on your Android device or clear the cache on an iPhone. This can sometimes resolve Plex app lagging issues caused by corrupted or outdated app data.

Tip: Close any other apps that are using a lot of bandwidth. This will free up bandwidth for Plex.

13. Uninstall and reinstall the Plex app. If nothing else has worked to this point to fix Plex loading slowly, take the time to completely uninstall Plex from your Android or iPhone. Then reinstall the Plex app on your device.

14. Report the issue to Plex: If none of the above solutions resolve the slowness, contact Plex’s support team and report the issue. They can investigate the problem and provide further assistance.
