Male Boss Stopped Holding Our Meetings in His Office - WHY?

My boss and I used to meet in his office when I first started traveling to our main office (I work remote). He would invite me into his office and would shut the door and we would have our 1:1 meeting.

The last two months, he has been avoiding his office and walking me into a conference room and leaving the door open. I wonder why? Can’t figure out what would cause this change.
