1. Check your network connection
The first thing to assume is problems with the Internet in general. Try to open any other site other than YouTube. If nothing loads, turn off your router for 10 seconds. Then start again and try to open the site. If the Internet is there and only YouTube does not work, move on.
2. Check YouTube availability
There are times when YouTube crashes due to problems with Google servers, despite their reliability. It is worth making sure that maybe the problem with YouTube is not only with you but with all Web users in general. To do this, try to open the site not only on your computer but also on your smartphone via a mobile connection. If it is available, then your ISP has a problem. Another option is to open one of the services to choose from: Down Detector and Down For Everyone or Just Me. Type youtube.com into the box and press Enter. If the service tells you that YouTube is not available to all users, there is nothing you can do. Just wait for Google to fix it. If it turns out that the problem is only with you, continue to move along this list.
3. Find out if YouTube is available in your area
This can be checked with the Down Detector. Type youtube.com, press Enter, and then Crash Map. And you will see in which countries the service does not work for some reason. If YouTube isn’t available in your region, use one of the VPN browser extensions or apps for iOS and Android to regain access to the service.
4. Disable and re-enable Wi-Fi and mobile connection
This is the easiest thing to do. You may be having internet problems and restarting the connection might help. Turn on airplane mode for a minute and then turn it off.
5. Connect to another wireless network
If you are not at home, but in some cafes, there may be problems with the local Wi-Fi network. Connect to one another.
6. Restart your device
Many problems can be solved in this simple way. Press and hold the power button until the shutdown menu appears. Then select the “Reboot” option.
7. Update your operating system
On older versions of the OS, you may experience problems with YouTube and other applications, so be sure to update. On Android, open System → Advanced Settings → System Update. On iOS: “Settings” → “General” → “Software Update”.
8. Open YouTube in a browser
There may be a problem with the YouTube app. Try opening the desired video in a mobile browser such as Chrome.
9. Update the YouTube app
Older versions of the app may not work properly. So go to Google Play or the App Store and make sure you have the latest version of YouTube installed.
10. Synchronize the date and time
The YouTube app may experience problems if the date and time on your device do not match the date on Google’s servers. Therefore, make sure that the smartphone downloads the correct time from the network. On Android, this is done as follows: open “Settings” → “System and device” → “Advanced” → “Date and time” → “Network date and time”. On iOS, tap Settings → General → Date & Time → Automatic.
11. Clear the YouTube cache
On Android, tap Settings → Apps & notifications → Show all apps → YouTube → Storage → Clear data. On iOS, the best way to do this is to uninstall and reinstall YouTube from the App Store. By the way, you can try the same on Android.
