ALEHover displays nothing for me

[WhiteBlackGoose]

Hello!

I'm trying to use ALE for C# using Omnisharp server. Here's what it displays in VSC when hovering over a method:

However, not in nvim (see, my cursor is set to the second character of Clear method. I then run command :ALEHover and nothing hapens)

Any idea what I did wrong?
