My online media sources page looks like screenshot above. I can’t access Free Live TV or Movies. I use Raspberry Pi 4 8GB as my media server. I don’t use VPN. I was using ‘Brave Shields’, ‘Decentraleyes’ and “Privacy Badger”. I turned them off and tried again but result was the same. I cleared cookies but it didn’t work neither. I am not sure what information I can give so please let me know if you need to know about something I didn’t mention.
Anyway, I checked console logs on my browser for more information and saw some errors.

I tried to open those link in my browser and got “Error 1020”
I couldn’t find similar post about this error on forums nor the way to overcome this error. Help would be really appreciated. Thanks in advance. (and sorry for grammatical issues)
