Unable to login into MacBook Air

welcome to the Apple (user-to-user) Community.

Re: "I have tried to reset the password with my AppleID, but it says there is a problem connecting with the server".

You may want to check if there any outages: Apple - Support - System Status (green dot = available : else try later)

or
