Streaming services are usually blocked because of your physical location. Here's the top reasons why:
Media services usually have licensing agreements that only allow them to show certain programs in certain geographic areas/countries.
Governments may block certain websites or services which are not inline with their values or interests.
Your work or school network may have a policy of blocking content they feel is not necessary for your work or distracting.
