Yes — Plex is still supported on various Western Digital (WD) “My Cloud” and related NAS drives — but whether it works on your specific device depends on the model, firmware, and whether WD continues to maintain the Plex app for that device. Here’s a breakdown of what’s true, what to watch out for, and what limitations there are.
What We Know
WD My Cloud OS 5 Models Support Plex
WD’s support documentation confirms that the Plex Media Server app can be installed and configured on many My Cloud OS 5 models. Examples include:
My Cloud Mirror Gen2
My Cloud DL2100 / DL4100
My Cloud EX2 Ultra / EX2100 / EX4100
My Cloud PR2100 / PR4100
The app is available from the WD Dashboard → Apps section.
My Passport Wireless Pro
This portable drive model previously supported Plex (you could install and configure Plex via its own “Media” section). Note the caveat: Plex transcoding is not supported on this device.
My Cloud Home / Single Bay Models
Plex is technically offered for “My Cloud Home” devices, but many users report issues. Examples include:
Plex “enabled” but the connection fails (e.g. “unable to connect securely”) after firmware updates.
Plex configurations missing or disabled in dashboards.
So support exists, but real-world reliability can vary.
What to Check for Your Device
To determine if your My Cloud or WD drive still supports Plex, verify:
Model: Is it on the list of supported My Cloud OS 5 devices (Mirror, DL, EX, PR lines)? If it’s a “Home” or older model not on that list, support may be degraded or no longer maintained.
Firmware version: Is it updated to the latest release from WD? Some Plex issues stem from firmware incompatibilities or missing update features.
Dashboard can install/manage Plex: Go to the WD Dashboard → Apps → Plex. If the Plex app is available, installable, configurable, then it's still supported. If not, the feature may have been dropped or disabled for your device.
Transcoding needs: Many WD devices support only basic streaming or “direct play,” not transcoding. If your media needs transcoding (i.e. the format isn’t compatible with your playback device), the experience may be limited.
Limitations & Common Issues
Security / Remote Access Problems: Users frequently report problems like “app.plex.tv unable to connect securely,” especially with My Cloud Home.
Plex version lag / outdated support: The Plex build on WD hardware is sometimes behind the latest Plex server version. New Plex features may not work or be delayed.
Feature limitations: As mentioned, many devices do not support transcoding, which means performance can suffer if the media isn’t already in a format the client device can play natively.
Support end-of-life: Older WD models may have been deprecated. WD's support for third-party apps (like Plex) comes with disclaimers: changes, updates, or even removal of app availability might happen.
Bottom Line
If you have a relatively modern My Cloud NAS (OS 5, Mirror/DL/EX/PR series), then yes — Plex is still officially supported, though with some constraints.
If you have a “Home” or older/single-bay device, Plex may still work, but expect potential issues or partial/peripheral support.
Always check manufacturer support pages for your exact model, and consider firmware updates or community forums for troubleshooting.
If you want, I can check Plex status specifically for your WD model (if you tell me which one), to see if support is current or if there are known issues.
