I just had the problem of being behind a Http/Https proxy and there is currently no option available to set this on the fire TV Stick.
Android offers this option at least since version 4 by default but they must have deactivatetd this feature intenionaly (region rights and such things).
But it is still possible.
1. Setup your AFTVS on a normal Wifi with internet connection ( if not already done)
2. Activate Apps from unkown sources and ADB
Settings --> System --> Developersoptions
3. Make sure your are connected to the same network as your pc.
4. Sideload following app:
AndroidProxySetter: github.com/jpkrause/AndroidProxySetter/releases How To sideload: aftvnews.com/sideload/#more-7959
//connect to device adb connect 192.168.1.184:5555 //check the connection adb -s 192.168.1.184:5555 get-state //start app adb -s 192.168.1.184:5555 shell am start -n tk.elevenk.proxysetter/.MainActivity -e host 192.168.56.1 -e port 8080 -e ssid PrivateWifi -e key Passw0rd
Please mind that ur on a linux based system and everything is case sensitiv.
For more options look here:
6. Going back to the home screen and Done.
Known issues: After some major updates you will need to set the proxy again, so just repeat step 4
It should also run on the normal AFTV but i got none so i can't test it.
All Credit goes to JPKrause who wrote that little app, I just happend to find it
