Connection error downloading UE 4.7.6

Hello,

So I am trying to download and install UE 4.7.6 but it always give me connection error “We are currently experiencing connections and are retrying”. Now I tried to change the launcher shortcut parameters to -http=wininet I also disabled my firewall, launched the launcher with admin privileges but it keeps giving me same issue. If I download newer version like 4.22 then it download just fine.

Is there any way I can get this specific version? Please help. Thank you!
