Endless loading of the mod in BeamMP

Hello, I ran into such a problem with a friend. I downloaded the mod and added it to the server.
Everything starts and works for me, but when
a friend tries to connect, the mod starts downloading, after it is completed, it starts again. After completing 2 downloads, 3 starts and so on

Which mod did you add to the server? the BeamMP.zip? that would not be good

I have added a mod for the bmw m3.I downloaded a mod from a website with mods.I have other mods from this site and they work fine. The problem only occurs with some mods.

The problem turned out to be that the friend did not have enough memory on the computer. But thank you all for your help.
