My Cloud OS5 and Plex

**My Cloud OS 5** (used in WD NAS devices like My Cloud EX2 Ultra, PR4100, etc.) supports **Plex Media Server**, but many users face setup, compatibility, and streaming issues.

Here’s everything you need to know about **My Cloud OS 5 and Plex**:

### ✅ **Plex Compatibility with My Cloud OS5**

WD officially supports Plex on **select NAS models** running My Cloud OS 5:

| WD NAS Model | Plex Support | Notes |

| --------------- | ------------ | --------------------------------------------------- |

| EX2 Ultra | ✅ Yes | Limited transcoding (no hardware acceleration) |

| PR2100 / PR4100 | ✅ Yes | Better for media streaming due to faster processors |

| EX4100 | ✅ Yes | Moderate performance |

| My Cloud Home | ❌ No | Not compatible with Plex |

📌 **Important**: Only **My Cloud OS 5** devices are supported for ongoing Plex use. WD discontinued My Cloud OS 3 support, and OS 5 requires a complete firmware upgrade with cloud rebuild.

### 🔧 **Common Problems with Plex on My Cloud OS 5**

1. **Plex Not Showing in App List**

* Sometimes Plex is missing in the My Cloud dashboard.

* **Fix**: Go to *Apps > Install Apps > Add App manually* and upload the `.bin` file from Plex's website (WD NAS section).

2. **Media Not Scanning or Showing Up**

* Caused by incorrect folder permissions or wrong library path.

* **Fix**: Make sure Plex is pointed to shared folders like `/shares/Public/Movies`.

3. **Playback Issues or Buffering**

* EX2 Ultra struggles with transcoding 1080p or 4K.

* **Fix**: Use “Direct Play” mode, or transcode on a more powerful device using Plex Pass features.

4. **Plex Not Updating Automatically**

* WD App Store doesn’t always have the latest Plex.

* **Fix**: Manually download the updated `.bin` from [Plex Downloads for NAS](https://www.plex.tv/media-server-downloads/#plex-app) and upload it via the dashboard.

5. **Plex Server Not Starting**

* May occur after firmware updates.

* **Fix**: Reinstall the Plex app, restart the NAS, and re-enable the Plex server from the dashboard.

### 🧠 Tips for Smooth Plex Experience on My Cloud

* Use **Plex Pass** only if using features like Live TV or remote access.

* **Avoid transcoding** on EX2 Ultra or lower—stream compatible files (MP4, H.264).

* Organize files properly (`/Movies/MovieName (Year)/MovieName.mp4`).

* Schedule regular **metadata refresh** during off-hours.
