I have a problem with link

Today I wanted to play in VR with my headset except that it was impossible to connect to a link with a cable except that yesterday I played in a cable link and I had no problem and from one day to the next it no longer worked, after I know that just before stopping playing I switched to air link because the games were buggy a little so I wanted to see if air link was better but then I stopped playing so today when I went to meta quest link (application) I saw that in my devices I no longer had my quest by cable link connection and I tried to put it back by selecting my quest 2, then cable link and there I tried everything but it no longer wanted to detect my headset while it worked very well yesterday, could I have some help please?
