Where can i watch the whole series?

Me and my friend decided it would be a fun idea to watch Ash's travels from episode 1 to his finale now there's a definitive end. So we were wondering where exactly the whole show was streaming. I worry it'll have to be a case of hopping between different services but hoping that won't have to be the case.

(I don't mind having to use a VPN but don't just say pirate it. I'm looking for official channels)
