After I downloaded the mod it works fine in single player worlds but after I connect to a vanilla server the F7 does nothing.

I tried to enable or disable caching, also removed all the other mods except for cloth config and light overlay but it didn't help.

mod jars:

• cloth-config-forge-4.0.1
• light-overlay-5.4.1

Minecraft version: 1.16.1
