VGG transfer learning error

I'm training a VGG network using transfer learning approach. (fine-tuning) But while training the dataset, I found the following error where it stops the training process.

ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

Can someone please help me to identify the issue here.

When it's trying to download the weights of vgg16, the error is shown due to connection break. Try to download weights manually. (link: https://github.com/fchollet/deep-learning-models/releases/download/v0.1/vgg16_weights_tf_dim_ordering_tf_kernels_notop.h5)

Once the weights are downloaded put it in the folder called 'models' which is in keras folder. keras folder will be hidden by default.

PathToFolder: C:\Users\UserName.keras\models.

After this setup, try to run the code.
