Dark and Darker is a difficult dungeon-crawling adventure for a small group of players who wish to escape the horde of undead creatures and human players who are also looking for a quick exit. Here's all you need to know about how to fix the Failed to connect to server error in Dark and Darker.
What can you do about the Dark and Darker Failed to Connect Error?
The first thing you want to do about any server connections is to check into what is happening with the Dark and Darker servers. There's a good possibility that the game's creator, Ironmace Games, is having difficulties, and it's likely that the servers will restart.

The team at Dark and Darker is able to check out their Twitter page to see what they're talking about. More likely than not, the team has shared that the servers are down for some reason or another, such as they're working on a hotfix or some other problem on their end.
The next step is to check out the Dark and Darker Discord page and see if others have similar issues. If they are, the issue might still be on the developer's end, and waiting it out is the best answer.
When the issue only happens to you, we'll recommend that you close down Steam, restart the client, and try again. This might take you a minute to complete, and it might indicate there's a patch that the Ironmace Games team is working on, so you'll not be able to play the game until you have this download.
The majority of the issues stem from the development team not having the game servers up, so regularly check Twitter and speak with other Dark and Darker players to see if they are experiencing the same issues.
