Games do not react?

When I'm running Overwatch or Fortnite games it was free and fluent but at some point I can't move, for example at Fortnite, I can still turn and aim the gun but nothing else and the other players are just running out. What can I do there? It was not like that two days ago

PS: I do not know if this is relevant but I give my PC over my mobile Internet.

Sounds after disconnection. It is best to play over Lan cable. 🙂

I've already tried that is exactly the same but thanks anyway

Is most likely on the Internet
