Hello. We are currently investigating reports of players not being able to enter WoC. We will provide an update when we have some news. I have a couple things you can try, but I'm not optimistic these will help.
Try deleting the personal saved data for NHL 25. It's possible you could lose any offline saves and changes to settings. Normally, those will download from the cloud, but I can't guarantee that will happen. Go to Settings/Storage/System. Locate NHL 25 and delete the saved data.
I'd like you to power cycle your equipment with the following steps: unplug your modem/router and console. After 2 minutes plug in the modem/router. Let them come back online completely. Then plug in your console and start it up. Let me know if that helps or not.
