The Season 3.5 balance patch was launched for Street Fighter 5: Arcade Edition on April 3rd. Since then, many of us have had some time to enjoy a slightly altered meta than the one that was present during Season 3.0.

Unfortunately, there are some people out there that have reported that they've been unable to play online since this new patch has dropped. One of our readers, Blackoshinomi, has informed us that he was once one of these affected users. I've taken notice that there are still people in our comments section that have been having issues.

Luckily, he was able to figure out a solution that permanently solved the problem for him. He even created a video that demonstrates how this was done, step-by-step.

First he shows the phenomenon that was previously plaguing him as it does for other users. While trying to connect to Street Fighter 5: Arcade Edition's server, he gets a message that is labeled "21001."

By venturing into the PlayStation's settings, users are able to make alterations that fixes this problem. All you have to do is set your "Primary DNS" to "".

After the jump, you can see the video that shows exactly what to do. Special thanks to goes out to Blackoshinomi for figuring this out and sharing it with everybody.
