Fine-tuning frozen, no message(s) returned

A few days ago, I ran a binary classification fine tuning problem through the OpenAI API with no problem. For the last 48 hours I have been trying to run a multi-class classification problem using similar calls to the API. However, I get stuck at this step:

openai api fine_tunes.create -t "content_relevance_prepared_train.jsonl" -v "content_relevance_prepared_valid.jsonl" --compute_classification_metrics --classification_n_classes 21

This has been running for over 24 hours with absolutely no message coming back (no information about being in a queue, nothing).

Have I done something wrong, or is there an issue with demand at the moment? What’s frustrating is that there is no information coming back at all, so I am completely in the dark as to why this command is frozen.
