Sounds like a Northern to North Eastern European accent to me. But I will say that YouTubers have their own accents that permeate different genres of videos as well, which can add ambiguity. My favourite accent tidbit is the English voice of the Shinkansen in Japan. It is voiced by an Australian, imitating a Canadian, who was imitating a British accent. The result is a totally ambiguous accent that sounds almost disconnected from geography. I say that as an Australian with a british twang.
