DMX not working

Hello, I am experiencing an issue with my sequence triggers. After I press a trigger die lighting sequence doesnt get started. The sequence also isnt working in unreal when i play the sequence. Previously, everything worked as expected, but now the fixtures do not react when adjusting parameters like Pan or Tilt inside a Level Sequence. Even in a newly created sequence, there is no movement. The Moving Head is placed in the level and assigned to a Fixture Patch from a DMX Library. It seems that the fixture is no longer responding to values coming from the Sequencer. Thank you.
