Do you know if this method was there since the Paper ping event was added? If not we should add some fallback logic. Also it needs to be copied in the new Paper module (with no fallback logic, since it's 1.21.8+ only). Thanks for the PR, I will pick it up later if you're no longer interested.

Thanks for the clarification! As far as I know, PaperServerListPingEvent was added in 1.12.2 and getClient().getVirtualHost() has been available ever since, so no fallback logic should be necessary.
I won’t be able to make further changes quickly due to schoolwork, so please feel free to take over the PR if needed.
