                <FaVk />
              </a>
...

Make sure you are importing correct icon name from "react-icon"

It looks like you imported correct icons in this code snippet but checks your all importing expression.

I'm having same problem with SSR on nextjs. It's the <IconContect.Provider>. Same as #235
