I would be helpful if you posted a link to a sample game, indicating the move when you tried to execute an en-passant capture.
Why I can't en passant ?

It should have been possible on that last move. It is possible that you had a connection issue that prevented the move before you ended up losing on time.

that's why I post this on forum because its very confusing. As you know, I even can't do en passant in daily tactics.

You're doing it wrong.
You have to move your pawn diagonally to the square it's attacking. In the example game you posted, you would simply move your pawn to the f6 square and the black pawn will disappear.

Are you doing what Dark_Army suggested? Trying to move the pawn to the square it will end up on? If so, are you on the website (if so, what browser and version) or on the app (if so, device type and version)?

Also, try to take in analysis mode? It is possible that you need to take more like suggested and you can figure that out with trying to take in different ways in analysis mode.

I would be curious to know whether you can successfully do this in analysis mode (drag & drop, touch piece, touch destination) or not?

Are you trying drag and drop? Or touch the piece, touch the destination square?

I'd realized in my several last game I had en passant condition but I couldn't capture my rival's pawn? I wonder there is any system trouble because it never happen to me before. Or maybe chess.com has setting for disabling en passant? any explanation about that?
