Lichess not responding to fen notations

Earlier I used to use the "Analysis Board" for pasting the new fen notation for creating new positions whenever I want to teach students. It used to work wonderfully showing new positions. For the last 10 days or so, even though I paste correct FEN notations, it says: invalid fen. When I paste the same notation in some other pgn editors, I get the positions correctly. REQUEST THE CONCERNED TO TAKE ACTION IMMEDIATELY TO CORRECT THIS PROBLEM. THANKS

WHY ARE YOU WRITING IN CAPS?

Please paste an example FEN here that doesn't work on the analysis board.

I am pasting this at 11.44 am in India. Even at 11.43 am I checked by pasting this in Lichess Analysis Board.
It says "invalid fen". But the same fen notation works very well in other pgn editors. - T R Shankar

Try 5r2/p3Qnkp/1p3Np1/2p3P1/3q4/5p2/PP3R1r/3R2K1 w - - 0 1
