Week 3 lab: SageMaker pipelines to train a BERT-Based text classifier

I was able to get to the lab and go through most of it. After a point, my internet dropped and now I can not get to the lab. I tried following the instructions to log out and log back in but to no avail. Is there a different forum I need to raise this issue on?
