Minecraft block can't be placed with / setblock?

I have built a redstone technique on my Minecraft server (1.16.2, Spigot) (but I'm on it with version 1.16.3, with the ViaVersion plugin), in which a command places a block at a certain point.

/ setblock 83 82 115 minecraft: redstone_block

This place (where the pumpkin is)

Minecraft block can t be placed with setblock

But that did not work (i.e. The block was not placed). When I entered the command by hand, the following message came in the chat: "Block could not be placed".

How can I fix the problem?

Ar

Hm probably not because of the plugin try the whole thing in single game mode and see if it works
