1. The bad internet connection

Connecting the device to a stable network connection is the primary condition of playing a video on YouTube. Hence, you need to check the internet connection on your computer or mobile phone first when the YouTube video cannot play error occurs. Except for that, here are also some other suggestions for you:

- Disable other applications: Using several applications on the device would take up some flow of the web so you can close down some of them to free up bandwidth and use a speed-testing tool to verify that the connection you are using is fast enough.

- Switch to a lower quality stream: A lower quality stream requires less network flow and slower internet speed so that you can attempt to switch the quality stream when the network is not stable. Just click on the quality button to change it.

2. The browser cache interrupts the running of YouTube

Another possible reason for the sluggish YouTube video loading or buffering is the browser cache. When the memory of the browser is full of temporary internet files, it will hold you up greatly. Thus, you'd better clear the browser caches regularly.

- On Android phones, you can navigate to the Settings> Apps/Application Management and then select the browser from the listed applications. On the next page, you can simply tap on the option Clear cache and Clear data to remove the browser caches.

4. Firewalls or other security tool blocks YouTube

The firewalls on computer or security tool on the mobile phone can protect the safety of the device but it would block some applications like YouTube sometimes. So to solve this problem, you can check within your installed security software to make sure that YouTube is listed as an authorized website that is allowed to operate without interference.

5. Enable JavaScript

YouTube will become crappy if JavaScript is disabled on the device. That's because several components of YouTube work without reloading the page and require JavaScript so you need to turn it on to make the YouTube run normally. Normally, the methods to enable JavaScript in different browser are disparate. And here, we would like to take Firefox as an example:

* Type in "about:config" in the address bar and press Enter.

* Next, a warning message would appear. You just need to click "I'll be careful, I promise" to continue.

* Now you can search for "javascript.enabled" in the search box.

* Toggle the "javascript.enabled" preference (right click and select Toggle or double-click the preference) to change the value from "false" to "true".

* Click on the Reload current page button of the web browser to refresh the page.

6. The device is senescent

YouTube stops to support aging devices now so if your device is not supported by the YouTube anymore, your only option to fix the error is to upgrade the device.
