This post will show you how to fix “An unknown error has occurred. Check your URL and connection” within Downloader.
Downloader is the most popular application that allows side-loading APKs onto the Amazon Fire TV or Firestick. This free application is used most notably when installing Kodi, Terrarium TV, and SET TV on the Fire TV or Fire TV Stick.
You may encounter the above error on the Fire TV 3 when attempting to download or install applications that aren’t available within the Amazon App store. The reason for this error is because permissions aren’t granted for file access upon first installing the Downloader application.
If you don’t allow for Downloader to access files on your Fire TV, there is now way for the application to download and install applications.

Warning! Protect Yourself With A VPN
Most cord-cutters use a VPN and rightfully so.
The free streaming applications, addons, and paid IPTV services that you use are usually hosted on insecure servers.
Without a VPN, your IP Address is being logged.
Your IP Address points back to your location and identity which compromises both your privacy and security.
Your current identifying IP Address is 18.215.185.97 – When you use a VPN, your real IP address will be converted into an anonymous new one.
A VPN will provide you with an anonymous connection to the Internet.
This will prevent your Internet Service Provider, app/addon developers, government agencies, and any 3rd party from logging what you’re accessing online.
The most popular VPN among cord-cutters is IPVanish due to their blazing fast speeds and zero log policy.
Its important to use a VPN that is fast since we are streaming large HD files. Its also crucial to find one that keeps no logs of what their subscribers access while online.
Setting up IPVanish VPN on your streaming device is simple!

Step 1 Register for an IPVanish VPN account by clicking the link below.
This exclusive link provides you with a hefty discount, only available to TROYPOINT visitors like you.


Step 2 – Hover over the search icon on your Firestick, Fire TV, or Fire TV Cube and type in “Ipvanish”
You may also find the IPVanish App in the Google Play Store for those of you who are using Android TV Boxes, phones, and tablets.

Step 3 – Click the IPVanish VPN option that appears.

Step 4 – Click the IPVanish icon under Apps & Games.

Step 5 – Click Download.

Step 6 – Click Open.

Step 7 – Enter your username and password to login. Your username is the email that you used to register for IPVanish service with and your password is automatically generated and emailed to you.

Step 8 – Click Connect button.

Step 9 – Click OK for Connection request if it appears.

Step 10 – You will notice that your IP Address changes along with location of connection. You are now operating anonymously through your device.
Click the Home Button on your remote and the VPN will remain running in the background.

Congratulations! You are now protected by a VPN which means everything that you stream or access through your Firestick or Android TV Box is hidden from the rest of the world.
If you ever need to stop the VPN service, simply re-launch the application and click the DISCONNECT button.
