Seems like connecting to the server does not register the Spectrum Multiblocks.

Do both server & client run Spectrum 1.6.12-1.19.2-leisure_time (probably yes, but does not hurt to check)

Other than that I got nothing, I am afraid. I can only suggest removing mods and check when it starts to work. As soon as we know the exact combination of mods that cause this I'll look into that and work on a fix.
