Slow downloading of linux version of station

I am trying to download latest version of station for linux. The file is hosted on AWS S3 storage. I am getting only 30kbps but my plan is 100mbps. I can wait for it complete but the problem the link gets expired when the download is on 112mb/130mb. Tried 3-4 times, same problem. Please look into the matter.

PS: I dont have any net issue I am getting my normal download speed when downloading anything else on the internet.
