You might reply to yourself, to raise awareness of your question.

The answer to it is that the guys running the server has "white listed" it due to maintenance issues, and therefore has limited who can join the server.

In this particular case the Wikicraft server is trying to be updated to 1.0.0, but there have been some issues in this upgrade. As such, it continues to stay white listed until Dblcut3 finds suitable solutions.

In another thread you can find the invite to the Discord channel for Wikicraft, where Dblcut3 is announcing relevant progress in the update process.
