SAP Download manager

Dear Teachies

I am try to download WEBCUIF 700 files from service market place of size 15MB

I noticed that after 13 MB download , it is not getting fully downloaded to 15 MB (mean only 13 MB is downloaded)

I checked the authorization for S user ID i have the download authorization

Even from SAP download manger it partially downloaded for two days and it is still processingn but diidnot got any error.

Internet connectivity is fine

I am confused i never faced this issue

Thank YOu
