The main issue is it takes a long time for neuroner to load pre-trained model and initiate itself before getting ready to process input data and generate responses, leading to "504 gateway" error. But after loading the pre-trained models, neuroner can generate responses in an expected manner. It's always the first request that led to "504 gateway" error. Neuroner needs to be initiated(including loading the pre-trained models) before receiving the first input data.
