How to Fix “A Communication error has occurred.” in Street Fighter 6?

Street Fighter 6 Communication Error is a prevalent issue that has been disrupting gameplay for many users across the world. This error is caused by a connection interference between your gaming device and the game’s servers, hindering your ability to engage in online matches and utilize multiplayer features. The problem can manifest in multiple ways, from sudden disconnections during gameplay to complete inability to log into the game.

 

What causes this error?

This error can be attributed to a variety of factors, each affecting the game’s ability to maintain a stable connection with its servers.

Network issues are often the primary culprit, whether it’s an unstable Wi-Fi connection, firewall restrictions, or even server-side problems from the game’s end.

Cross-play between different gaming platforms can also cause network inconsistencies, leading to the potential occurrence of Communication errors.

You should also consider that your network is unable to connect to the servers due to some regional restrictions or firewalls that might require a VPN.

How to fix this error?

There are a few fixes that you can do in order to fix the Street Fighter 6 Communication error. Most of these fixes are related to the network connection because this is the principal cause, so here is how you can fix this issue:

1. Check the server’s status

Start by checking the official Street Fighter 6 site. This page is dedicated to showing all the upcoming maintenance periods. It contains all the information needed about the servers and the upcoming updates of the game.

If you want more information about the servers, you can also visit the official Street Fighter Twitter account. Here you will be able to see all the latest updates posted related to the game. Check the page and look at the newest posts to see if they indicate anything about an ongoing issue.

If you find out that the servers are down, you can’t really do anything to fix this besides waiting until the developers fix this issue. 

If the servers are working perfectly and you don’t see any problems, that means the issue is caused by something else.

2. Disable Cross-Play (Temporarily)

Cross-play feature expands the player base, but can also have a negative impact because it makes the game unstable in certain game modes.

To prevent this, all you need to do is go to the game’s settings and disable the feature. Here’s how you can do this:

  1. From the main menu of the game, access the Options.
  2. Go to the Game tab and look for the Crossplay option.
  3. When you see it, access it and click on Yes to disable it.

  4. Close the Options and enter a match to see if the Communication error still appears.

3. Forward ports for Street Fighter 6

Another cause for this issue could be that your router is unable to make the connection to the server due to not supporting the UPnP (Universal Plug and Play) technology. In this case, you will have to manually forward the ports for Street Fighter 6 to ensure that the network works properly.

By forwarding the ports, you’re telling your router to prioritize network traffic for this game. This can improve the overall connection of the game and will fix this issue.

This process can be done from your router’s settings. It will be a bit different from router to router depending on the manufacturer, but the instructions should be enough to help you do it.

Here’s a guide on how to do this:

  1. You need to start by accessing the router’s settings on your browser using its IP address. In most cases, the default IP address is either 192.168.0.1 or 192.168.1.1. If it is not working, search online for instructions in your case.

  2. Inside the router settings, you will be asked for the credentials of your account. If you have changed the default credentials, you should be able to log in with admin as username and 1234 or admin as password. If it doesn’t work, look online for the default credentials for your specific router manufacturer and model.
  3. Now you should be able to see the router settings. Expand the Advanced menu and access the NAT Forwarding (Port Forwarding) section.
  4. Click on Virtual Servers and you will see an Add button. Click on it to proceed.

4. Set the DNS settings for Cloudflare

Changing the DNS (domain name servers) that you are currently using to the DNS provided by Cloudflare is another good way of ensuring that you stay away from this error. 

Switching to this DNS server can improve your connection speed, reduce latency, and provide a more stable connection, but most importantly can make the Communication error disappear.

Changing your DNS settings is often a simple process that involves going into your device’s network settings and manually entering the IP addresses of the DNS servers you want to use.

5. Use a VPN

Users have reported that this issue could appear because of an internet connection problem triggered by your ISP.

In this case, you can try to use a VPN in order to use a different IP when trying to join the server.

Note: A VPN masks your IP address and routes your internet traffic through a server in a location of your choice.

But before buying a subscription to service of this kind, you should know that using a VPN can increase latency, depending on the distance between you and the VPN server. Always choose a server that’s geographically close to you or the game’s servers for optimal performance.

We recommend you start by getting a free trial of a VPN to see if you are able to play the game that way. Here’s a list of some free VPNs that are excellent for games:

If the VPN stops the Communication error from appearing in Street Fighter 6, you should then contact your ISP and ask him to resolve this problem.

6. Disable Internet Protocol Version 6

Disabling the Internet Protocol Version 6 feature in your PC settings might end up fixing the Street Fighter 6 Communication error. 

If your router doesn’t fully support IPv6, disabling this protocol will force all connections to IPv4 which might make the issue go away for good. All you need to do is to disable the IPv6 from your internet connection’s Properties.

Here’s how you can do it:

  1. Open a Run dialog box by pressing the Windows key + R and type ‘control‘ to open the Control Panel.
    Opening Control Panel
    Opening Control Panel
