How to Fix: 401 error when accessing Plex Media Server

The Plex Media Server error 401 Unauthorized occurs when an unauthorized user attempts to access the server's web interface or mobile app. This issue affects users who have set up their Plex account and enabled remote access but are unable to connect to the server using a web browser or mobile device.

This error can be frustrating for users who have successfully set up their Plex Media Server on an AWS EC2 instance, as it prevents them from accessing their media library remotely. In this guide, we will explore the root causes of this issue and provide steps to resolve it.

💡 Why You Are Getting This Error

• The primary reason for the 401 Unauthorized error is that the Plex Media Server is not configured to allow remote access through the web interface or mobile app. Although remote access has been enabled on the server, the necessary configuration settings may not be in place to allow external connections.
• Another possible cause of this issue could be a misconfiguration of the security groups or firewall rules on the AWS EC2 instance. If the required ports are not open or if there are any issues with the network connectivity, it can prevent remote access to the Plex Media Server.

🔧 Proven Troubleshooting Steps

💡 Conclusion

To resolve the 401 Unauthorized error when accessing the Plex Media Server, you can try enabling remote access through the web interface or configuring the security groups and firewall rules on the AWS EC2 instance. If neither of these methods work, it may be necessary to consult with a network administrator or Plex support team for further assistance.
