Text saying "No compatible versions found" while installing curse forge mod

recently I wanted to check out a gun mod for my server, I tried to install Modern Warfare mod (idk if it was available for 1.16.4 server) but it said "No compatible versions found" and then I tried mrcrayfish's gun mod, and it again said "No compatible versions found" then I checked and I saw that it was available for 1.16.4

please fix it
