Jellyfin Discover Movies 500 Error: A Comprehensive Fix

Hey there, Jellyfin enthusiasts! Are you encountering the dreaded 500 error when trying to access the Discover Movies category? You're not alone! This guide will walk you through the issue, its causes, and, most importantly, how to fix it. Let's dive in and get your movie discovery back on track.

Understanding the 500 Error in Jellyfin

The 500 Internal Server Error is a generic HTTP status code indicating that something went wrong on the server's side. In the context of Jellyfin, this often means there's an issue within the application or its plugins that's preventing the server from fulfilling your request. When you encounter a 500 error specifically with the Discover Movies category, it points to a problem with the home screen sections plugin or its interaction with Jellyfin's core functionalities.

Common Causes of the 500 Error

Before we jump into the solution, let's explore some common culprits behind this issue. Understanding the potential causes can help you prevent similar errors in the future and troubleshoot more effectively. So, when you face this 500 error, it is always good to look at these common causes:

  1. Plugin Compatibility Issues: Plugins extend Jellyfin's functionality, but sometimes they can conflict with the core system or other plugins, leading to errors. The home screen sections plugin, which is responsible for the Discover Movies section, is a frequent cause of such conflicts.
  2. Date and Time Parsing Errors: The error log often points to System.FormatException: String '' was not recognized as a valid DateTime. This indicates that Jellyfin is having trouble parsing date or time information, which can occur if the system's date and time settings are incorrect or if a plugin is providing invalid date formats. This is a common 500 error cause.
  3. Corrupted Plugin Data: Sometimes, the data used by a plugin can become corrupted, leading to unexpected errors. This can happen due to various reasons, such as improper shutdowns or software bugs.
  4. Jellyfin Version Incompatibility: Outdated or incompatible versions of Jellyfin or its plugins can cause issues. Always ensure that your Jellyfin server and plugins are up-to-date and compatible with each other to avoid facing a 500 error.
  5. Server Resource Constraints: If your Jellyfin server is running on a system with limited resources (CPU, RAM), it may struggle to handle complex requests, resulting in errors. This is especially true if you have many users or are transcoding multiple streams simultaneously. This constraint may lead to 500 errors.

Knowing these causes will make you efficient in fixing 500 errors and makes you a Pro user!

Step-by-Step Guide to Fixing the 500 Error

Now, let's get down to business and fix this pesky error! Follow these steps to troubleshoot and resolve the 500 error in your Jellyfin Discover Movies category.

Step 1: Check the Jellyfin Logs

The first and most crucial step is to examine the Jellyfin logs. These logs contain valuable information about what went wrong and can provide clues to the root cause of the issue. The error log provided in the initial report is a great starting point.

  1. Via the Web Interface: You can access the logs through the Jellyfin web interface by navigating to Dashboard > Logs. Here, you can view and download the logs.
  2. Directly from the File System: Alternatively, you can access the log files directly from the file system. The location of the logs depends on your Jellyfin installation and operating system. Common locations include:
    • Linux: /var/log/jellyfin or /config/log within your Jellyfin Docker container.
    • Windows: The Jellyfin program directory (e.g., C:\ProgramData\Jellyfin\Server\logs)

Analyzing the Logs

Once you have access to the logs, look for error messages that coincide with the time you encountered the 500 error. Pay close attention to entries that mention System.FormatException, DiscoverMovies, or the home screen sections plugin. The error message in the provided log, String '' was not recognized as a valid DateTime, is particularly significant, suggesting a date parsing issue.

Step 2: Restart the Jellyfin Server
