Slow connection, download cancel itself after about 40-50 min

I have a pretty slow connection (~1.2Mo/s). When trying to download a trained model (~4G), the download cancel itself after about 40-50 min. I don't know exactly but it might be caused by a session expiration. Does someone knows a fix ?

Try a different time of the day. I noticed that evenings (GMT+1) are slower then in the morning. Also weekends are slow. But in general the download is just very fast
