I found out that the problem is not from IDM but from downloadly itself, I tried to download another file (5Gb) it took only 7 to 8 minutes, on the contratry the link from downloadly which is only 2Gb it took 2.5 hours even with multiple connections only two that are connected.
Anyway thank you bro for the guide surely will help for other upcoming downloads 😁
