fix The First Descendant upstream is not available

In The First Descendant, players have recently encountered a connection error known as "upstream not available," which prevented them from logging into the game. This type of error is common in large-scale online multiplayer titles and typically indicates a problem with the connection between the user's client and the game's servers, or between different services on the developer's end.

The First Descendant: "Upstream Not Available" Error

This specific error appeared shortly after the release of hotfix 1.3.1d on August 18, 2025. This hotfix was implemented to address several issues, including:

• The Battle Pass daily bonus EXP not resetting.
• The Battle Pass daily challenge not appearing after being refreshed with the same objective.

While it is possible that the hotfix introduced this new connection problem, the exact cause is not publicly known. However, the developers at Nexon were quick to acknowledge the issue and began working on a solution.

How to Fix the Error

Since the "upstream not available" error was a server-side issue, the mosteffective solution was for the developers to address it directly.Players reported that the problem was resolved by the development teamshortly after it appeared.

For future connection issues, or if you still experience this error, here are some general troubleshooting steps you can try:

• Check Server Status: Always check the official The First Descendant social media channels or website to see if the developers have announced any server maintenance or outages.
• Restart the Game and Your Router: A simple restart of both the game and your modem/router can often resolve temporary connection problems.
• Log Out and Log Back In: On the Nexon website, try logging out of your account and logging back in to refresh your session.
• Disable Crossplay: In the game's settings, you can try disabling crossplay, as this can sometimes cause connectivity conflicts.
• Use a VPN: While not a guaranteed fix, a VPN can sometimes help bypass network routing issues between you and the game servers.
