Unreal engine download stops after 17%

Just to make it clear, I’ve downloaded and used ue4 previously ! This is not the first time.
A few days ago I tried to download the latest 4.26 ( Windows ) and was getting 8-10mbps download speed but everytime around 17% it drops down to 0 and shows “Connection problem, please check your internet connection”. Whearas I have a perfectly working connection with no problem.
I tried waiting for a few days, restarted the download, tried downloading it from my 2nd PC and 2 other laptops - The same thing happens !
( I’ve tried downloading other versions but I’m facing the same problem )

I’ve tried all the solutions listed on the help page - nothing works !
Please help.
