Steam Content Servers Unreachable problem

[zero]

I was updating my Dota 2 game, and I suddenly noticed it stopped a few times after I continue to resume it, after watching what's happening, I suddenly got a message that 'Steam contents server unreachable(no internet connection.)' I have stable internet and decided to restart Steam itself, but it keeps happening after I tried it, so I decided to switch to a different region. Any ideas why this is happening? Thank you, and have a great day guys!
