I’ve been using Discovery Plus to watch some amazing documentaries and shows that you can’t find anywhere else.
It’s been working amazingly well and I’d invited a friend over to watch a food documentary that I knew he’d be interested in.
I found the show and started it, but it just showed me ‘Error 400.’
I tried closing the app on my TV and starting it up again, but it was the same error.
Naturally, I went online and looked through a few forums where users had the same issue and I found a few fixes that worked.
So, how did I fix this issue and get back to watching amazing food being made in parts of the world I may never travel to?
Discovery Plus Error Code 400 is caused by an unstable or slow network connection and can be fixed by restarting your router or by clearing cache and temporary data from the app.
Check the Discovery Plus Server
Before stepping into troubleshooting, make sure that Discovery Plus servers are active.
You can do this by checking out the “Discovery+ help” handle on Twitter, which is a support page for Discovery.
They will usually put up a tweet letting users know that their services are down and will retweet when the issue is resolved.
If this is the case, then you don’t have to troubleshoot anything.
Just wait and continue watching your shows once the service is back online.
If your streaming device is unable to communicate with Discovery servers, you will also see the Discovery plus Error 0C-C009, which you will need to fix first.
Check your internet connection
Make sure your network connection is working properly.
Check on your phone or laptop if you’re able to browse or download content.
If not, then you’ll need to reset your router.
Turn it off for about 15 to 20 seconds and then turn it back on.
This should clear any cache and temporary data that was causing issues with your router not connecting to the internet.
If you face an issue even after the restart, you’ll need to contact your service provider to find out if there are any other problems preventing network access.
Clear Discovery Plus App or Browser Cache
Clearing cache can fix certain issues by removing old temporary files that aren’t needed anymore.
To clear the cache you can follow the steps below.
Settings > Apps > Discovery Plus > Storage & Cache > Clear Data.
Settings > Discovery Plus > Reset Cache on Next Start.
On Amazon & Roku streaming devices,
Manage Application Settings > Discovery Plus app > Clear Cache.
Browser > Settings > Site Settings.
Once the cache is cleared from your device, open the app and check if you’re able to play content.
Re-install the Discovery Plus App
Another way to get the app working again is to re-install the Discovery Plus app.
Before doing that, however, close the app from the multitask view on your iOS or Android device and restart the app again.
You can also try restarting your phone and try opening the app to see if it works.
Also, make sure your app is on the latest version. If not, make sure to update it.
If restarting the app didn’t work, you might have some corrupted files or bugs.
You can fix this by uninstalling the app and reinstalling it from the Play Store or App Store depending on your device.
Turn Off the VPN
While VPNs do allow you to bypass regional restrictions on certain apps, some apps may not work with a VPN active.
Network instability could also cause Discovery Plus servers to take too long to respond to your device’s request to play a show.
This could lead to Discovery Plus Error 504, so keep an eye out for this as well.
If your VPN is on, turn it off, restart the app, and you should be able to browse through and play content.
If you prefer using a VPN however, check the VPNs product page to make sure they support the streaming apps that you use, otherwise you might run into these issues again.
Keep Discovery Plus Running Smoothly
I got my Discovery Plus app working after sorting out my network connection, but all these fixes will help sort out error 400.
Once you’ve got the app running, I’d recommend turning on auto-update or checking for updates every month or so to keep your app running smoothly.
Additionally, you’ll also need to keep your device up-to-date whether you’re watching on a TV, smartphone, or tablet to prevent any unnecessary bugs.
I’d also recommend checking out the nature documentaries from BBC that you find on Discovery Plus. They’re absolutely amazing.
And make sure your internet speed is sufficient and stable for streaming.
