MW3 CANNOT CONNECT TO THE SERVER

[UwU Slaying]

Hello, today i have a problem on MW3.
I can't connect to every server. I have an infinite load. I can't even go private.
When I use a VPN I can join the servers and start a private game.
Yesterday everything worked fine.
Thank you for your response.

Try to restart your router.

Hello. The next day everything works normally.
I must have just had a problem connecting effectively.
Thank you for your reply.
