Plex Media Server is one of the most significant methods to stream and organise your media library, but it, like all software, is vulnerable to problems. Plex customers frequently experience technical faults, such as buffering, server connection issues, and failed library updates. In this article, we’ll look at the most common Plex media server issues and how to resolve them successfully.

What is Plex Media Server, and Why Use It?

Plex Media Server lets you stream your movies, TV episodes, music, and images to any device. It’s a comprehensive media management solution that works across platforms, allowing you to enjoy your content on smart TVs, mobile devices, and even game consoles.

Despite its many benefits, Plex may face technological issues. Let’s go over the most common concerns and their solutions.

Frequent Plex Media Server Issues

1. Server Not Found

If your Plex app is unable to find your server, this could be due to network difficulties, firewall settings, or the Plex server not functioning properly.

2. Buffering During Playback

Does Plex repeatedly stop to buffer when you’re watching a movie? This is typically caused by sluggish network speeds, transcoding overload, or excessive server resource utilisation.

3. Certain Files Won’t Play

Some media files may fail to play because of unsupported formats, missing codecs, or Plex’s transcoding settings.

4. Library Won’t Update

Are newly added files not appearing in your Plex library? It could be a result of permission difficulties, inappropriate scan settings, or poor file organisation.

5. Remote Access Not Working

Plex allows you to stream content from outside your home; however, remote access issues are widespread due to firewall restrictions, ISP settings, or faulty router configuration.

6. Subtitles Not Showing or Syncing Incorrectly

Subtitles may display improperly, appear out of sync, or fail to load owing to format mismatches or faulty encoding.

7. High CPU Usage or Performance Issues

If Plex is using too much CPU, it could be because of excessive transcoding or poor server settings.

8. Login and Authentication Failures

Users may experience issues entering Plex owing to incorrect credentials, network conflicts, or authentication errors.

9. Problems After a Plex Update

Following an upgrade, Plex may stop working properly, introduce errors, or change essential settings.

Troubleshooting Common Plex Problems

1. Fixing Server Connectivity Issues

• Check to see if your Plex server is running after restarting it.
• Make sure your firewall isn’t preventing Plex.
• Check your local network connection and IP settings.

2. Reducing Buffering and Lag

• Reduce the streaming quality in Plex settings.
• Instead of WiFi, use a physical Ethernet connection.
• Enable hardware acceleration for transcoding.

3. Resolving File Playback Errors

• Convert unsupported files to a Plex-friendly format, such as MP4 (H.264).
• Check to see if the media file is corrupted.
• Ensure that Plex has permission to access the file location.

4. Ensuring Library Updates Work Properly

• Manually reload your library from the Plex dashboard.
• Confirm that Plex has access to the appropriate media folders.
• Use suitable naming conventions for media files.

5. Enabling Remote Access the Right Way

• Enable remote access in the Plex settings.
• Set up TCP port forwarding (TCP 32400) on your router.
• Disable any VPNs or proxies that may be blocking distant connections.

6. Fixing Subtitle Display and Sync Problems

• Use external SRT subtitles rather than embedded ones.
• Convert subtitle files to UTF-8.
• Plex allows you to manually adjust subtitle sync settings.

7. Lowering CPU Usage for Smoother Streaming

• Direct Play/Direct Stream reduces the amount of transcoding required.
• If your server is having trouble handling 4K content, consider upgrading its hardware.
• Optimise Plex settings to maximise efficiency.

8. Troubleshooting Login Failures

• Reset your Plex password if necessary.
• Before you log in, clear your browser’s cookies and cache.
• Try connecting to Plex over a different internet network.

9. Recovering from a Problematic Plex Update

• If the update produces problems, roll back to the previous stable version.
• Check the Plex community forums for reported update issues.
• Backup your settings before applying future updates.

To avoid frequent difficulties, use these best practices:

• Keep Plex Updated: Always use the most recent stable version.
