How to Fix Granblue Fantasy: Relink Endless Ragnarok Connection Failed Error (2026 Comprehensive Guide)

The Endless Ragnarok expansion has given Granblue Fantasy: Relink a fresh wave of life. New bosses, improved co-op content, cross-platform matchmaking, and more reasons to grind with friends have made it one of my favorite multiplayer action RPG experiences this year.

Unfortunately, there is one issue that keeps showing up for a lot of players—including me.

The infamous “Connection Failed” message.

Sometimes the game refuses to find a lobby. Other times matchmaking spins forever before kicking you back to town. I’ve also seen random disconnects in the middle of quests and endless loading screens that never move beyond the “Connecting…” message.

After spending far too much time testing different fixes, reading community discussions, and comparing what actually worked for other players, I noticed something important:

There isn’t one universal solution. The error usually comes from your network setup, matchmaking region, or platform-specific issues.

Below are the methods that produced the best results in real gameplay.

Why Does the Connection Failed Error Happen?

Unlike many online games that rely completely on dedicated servers, Granblue Fantasy: Relink mixes server communication with peer-to-peer networking during multiplayer sessions.

That means even if the official servers are online, several things can still interrupt matchmaking.

The most common causes include:

• Regional matchmaking problems
• Strict NAT or CGNAT internet connections
• Router firewall conflicts
• Cross-platform synchronization bugs
• Corrupted update files
• Temporary server congestion after major updates

In my experience, the problem usually isn’t your internet speed. A fast fiber connection can still fail if your network configuration prevents proper communication with other players.

Quick Overview of the Most Effective Fixes

If you’re on PC, I’d honestly begin with the Steam region trick before touching anything else.

Fix 1: Change Your Steam Download Region

This was the biggest surprise.

At first it sounds unrelated, but Granblue Fantasy: Relink appears to rely heavily on the Steam download region when searching for multiplayer sessions.

If your selected region has fewer active players—or is temporarily overloaded—the matchmaking system can fail repeatedly.

Changing it takes less than a minute.

Steps:

1. Close the game.
2. Open Steam.
3. Go to Settings.
4. Open Downloads.
5. Locate Download Region.
6. Choose another busy region.

Popular choices include:

• Japan (Tokyo)
• Japan (Osaka)
• Los Angeles
• New York

Restart Steam afterward before launching the game again.

I noticed matchmaking becoming noticeably faster after switching to Tokyo, although your results may vary depending on your location.

Fix 2: Replace Your ISP DNS

A surprising number of internet providers still use slow or overloaded DNS servers.

While DNS doesn’t directly improve your ping, it helps your system locate online services more reliably.

Two excellent free options are:

Changing these settings only takes a few minutes on PlayStation, Nintendo Switch 2, or even Windows.

If matchmaking constantly times out before finding players, this is definitely worth testing.

Fix 3: Check Whether CGNAT Is the Real Problem

This is something many players never think about.

Lots of ISPs now place customers behind something called Carrier-Grade NAT (CGNAT).

The downside?

Peer-to-peer games sometimes struggle to establish direct communication between players.

An easy way to test this is by using your smartphone.

Here’s what I recommend:

• Enable a mobile hotspot.
• Connect your console or PC.
• Launch the game.
• Try joining multiplayer.

If everything suddenly works, your home internet configuration is probably responsible.

In that case, contact your ISP and ask whether they can:

• Disable CGNAT.
• Assign a public IPv4 address.
• Improve your NAT type.

Many providers can do this without replacing your equipment.

Fix 4: Give Your Router a Proper Restart

We’ve all heard “restart your router.”

Most people don’t actually do a complete restart.

Instead of simply pressing the power button, try this:

1. Shut down your gaming device.
2. Unplug both the modem and router.
3. Wait at least one full minute.
4. Turn on the modem first.
5. Wait until every connection light becomes stable.
6. Turn on the router.
7. Reconnect and launch the game.

It sounds basic, but clearing cached routing information occasionally fixes strange multiplayer issues after large game updates.

Fix 5: Stop Using Public Matchmaking

When public matchmaking starts acting strangely, I usually skip it entirely.

Private rooms tend to be much more reliable.

Creating a private session is simple:

• Visit the Quest Counter.
• Select Online Play.
• Create a Closed Room.
• Generate a session code.
• Share the code with friends.

Instead of relying on automatic matchmaking, everyone joins directly.

It’s not ideal if you’re playing solo, but if you’re farming with friends, it avoids many of the current matchmaking bugs.

Fix 6: Verify the Installation

Large expansions occasionally leave behind damaged or incomplete files.

This can happen because of interrupted downloads or storage errors.

On Steam:

1. Open Library.
2. Right-click the game.
3. Choose Properties.
4. Open Installed Files.
5. Select Verify Integrity of Game Files.

Steam automatically replaces anything that’s missing or corrupted.

Console players should also clear their system cache after major updates.

It isn’t guaranteed to solve the issue, but it removes one more possible cause from the troubleshooting process.

Don’t Ignore Crossplay Issues

Crossplay has been one of the expansion’s best additions, but it has also introduced new networking challenges.

I’ve noticed sessions occasionally become unstable when players rapidly refresh matchmaking or when someone resumes the game after putting their console into sleep mode.

If you’re experiencing repeated disconnects:

• Fully restart the game.
• Avoid Rest Mode before multiplayer.
• Make sure every player has installed the latest update.
• Confirm everyone is playing on the same game version.

Even one outdated client can create unexpected connection problems.

What Usually Doesn’t Help

After trying countless suggestions online, these methods rarely made any noticeable difference for me.

• Reinstalling Windows.
• Buying a new router immediately.
• Reinstalling the entire game multiple times.
• Disabling antivirus software.
• Lowering graphics settings.

Unless you already know one of those is causing problems, they’re generally not the first things I’d recommend.

A Few Extra Tips

If you’re still getting disconnected regularly, these smaller tweaks can also improve stability:

• Prefer a wired Ethernet connection over Wi-Fi.
• Close bandwidth-heavy applications before launching the game.
• Avoid downloading large files while playing.
• Restart Steam before long multiplayer sessions.
• Make sure your router firmware is up to date.
• Check whether the game servers are undergoing maintenance before troubleshooting your own network.

These won’t magically solve every problem, but together they can reduce random disconnects.

Final Thoughts

After testing nearly every community suggestion, I kept coming back to one conclusion: the Connection Failed error is usually a networking issue rather than a game-breaking bug.

For PC players, changing the Steam download region consistently produced the best results.

Console players generally have more success after switching to reliable public DNS servers and making sure their NAT configuration isn’t too restrictive.

If none of those solutions work, the mobile hotspot test is probably the fastest way to determine whether your ISP is the real source of the problem.

The good news is that the developers have continued improving online stability with updates, so the experience has already become better than it was immediately after the Endless Ragnarok launch. Until matchmaking is fully optimized, a combination of the fixes above gives you the best chance of getting back into co-op without endless loading screens or frustrating disconnects.

Hopefully, your next session is spent fighting bosses with your party—not staring at another “Connection Failed” message.
