Here is a copy of the mail from NLnet. Oddly enough it refers to 2021-10-022 but the MoU is 2019-10-051 
It’s great to hear you want to pick up the tasks in the MoU again. The
ForgeFed project (2021-10-022) still has funding left that you can
claim. The hard deadline for claiming it is October 1st 2022. Any
funding not claimed by finishing tasks until then goes back to the EC.The work on ForgeFed is still very important.
