Connection Error

[elisetaragola]

Hi, for a school project I have to connect the YOLOv8 model for object detection with LabelStudio. I followed the steps as provided, and I can successfully connect the model with LabelStudio. I changed the labels to 'Biopsy', 'Lesion' and 'Hotspot' and used my own .pt file with trained weights. However, I can not get predictions in LabelStudio. I selected some tasks and pushed the 'retrieve predictions' button. When checking the logs of the docker container, I get a NewConnectionError. I added the complete output below. Do you know how to solve this? Or some tracks I can follow? Thank you!
