hub: Failed to download model

From couple hours ago, I tried to download a new model to make classification… but it gave me this message `

I tried to download an existed model to test the problem, but it gives me the same error! Any help ?? Note :I tried the image modules links on another PC and Internet connection… The links are not responding! could anyone try to test the module download process, which have been done by Retrain.py code ?
