The ‘Error setting up player: invalid license key’ issue appears when users play videos that were embedded using JW Player from their default browser. The issue is most commonly encountered when playing videos on Google Chrome.
What’s causing the ‘Error setting up player: invalid license key’ issue?
- Time and date are incorrect– This might seem like a weird issue, but a lot of affected users have confirmed that the problem can very well occur due to large time and date difference detected on your system and the network. As it turns out, JW servers might not allow connections to be established if the end-user time & date is way off. To fix it, all you have to do is adjust the date, time and timezone from the Windows menu.
- 3rd party firewall interference – It’s been confirmed that there are several different overprotective firewalls that are known to block JW embedded videos from playing. If this scenario is applicable, you can resolve the issue by establishing a rule to exclude your browser or by uninstalling the 3rd party tool altogether.
- Outdated browser – Several users have reported that the issue can also occur due to an outdated browser version that is incompatible with the JW player version that is installed on the website that you’re trying to visit. In this case, you can resolve the issue by updating your browser to the latest version.
- Corrupted cache data – Temporary files located in your browser’s cache folder can also cause this behaviour. In this case, you should be able to resolve the issue by clearing the cache and cookies of your browser. This can either be done natively from your browser’s settings or via a cleanup app like Ccleaner.
Method 1: Fix your computer date & time

Method 2: Dealing with the 3rd party firewall interference
As it turns out, the issue can also occur due to some kind of network issue caused by your 3rd party firewall or security suite. If you only see this issue occurring in your home, an office, school and any other kind of managed network, it’s probably because of some firewall rule that’s prohibiting the browser from establishing the required connections.
If this scenario is applicable and you’re using a 3rd party firewall component that you suspect might be overprotective, you can fix the issue by establishing a white-listing rule that will exclude Chrome from the list of filtered items. But the instructions on doing so will be different depending on which security suite you use.
One universal fix that will work regardless of your firewall component is to uninstall the 3rd party app altogether, just to see if the problem is still occurring. Here’s a quick guide on how to do this:
- Press Windows key + R to open up a Run dialog box. Next, type ‘appwiz.cpl’ in the text box and press Enter to open up the Programs and Files screen.
- Once you manage to get inside the Programs and Files screen, move down to the right-hand side pane and scroll down to the list of installed applications and locate the 3rd party firewall application that you suspect might be causing the issue.
