You are downloading from a server in China, maybe they are throttling IPs from India But seriously, if it is slow then you can download it directly from http://www.lotoo.cn/english/bottom/Service/Download/Hi_Fi_Music_Player/2020/0427/80.html and then follow instructions in zip file where to copy the fw file for local installation.
Hey, this was the second time I faced this issue while updating, so thought of putting up. But yes the throttling part may be true.
