Here’s the crux of the article in video form:
Nike, being the global leader for sneakers, always has a significant amount of traffic on their app, website, or other portals. However, this also means that even the slightest of issues can end up negatively impacting thousands.
Some are currently reporting multiple problems with the Nike store that are preventing them from making purchases.
Nike app, website, and SNKRS app not working
Nike users claim (1,2,3,4,5) that the official app, website, and SNKRS app have not been working for the past few days. Whenever they try to make a purchase, they are greeted with various error codes.

Yo @nike my snkrs app hasn’t allowed me to check out & is telling that there aren’t any sizes in any shoe i try to click on for over 3 days

The ‘Order not processed’, ‘404 Error’, and ‘A connection error has occurred’ are some of the most common error messages that currently trouble users. This happens even for those with high-speed internet connections.
The problem persists on both mobile and web versions of the Nike store. Several users are unable to participate in ongoing contests on the SNKRS app either.
Potential workaround
It appears that the issue has something to do with the type of internet connection that one uses. Some have confirmed that the Nike store starts working as soon as you switch from a Wi-Fi connection to mobile data.

While this is weird for sure, there is a chance that the Nike servers are unintentionally blocking access to Wi-Fi connections. Using mobile data can act as a potential workaround for the time being.
Unfortunately, Nike support is yet to comment on the issue where the official app, website, and SNKRS app are not working for some. We’ll keep an eye on this matter and update this story to reflect noteworthy developments.
