Can't access my account anymore?

At noon today, I was able to play with a buddy of mine without any problems. However, when I switched on my switch again and wanted to log in to Fortnite I could not get in anymore. I noticed it just now and therefore ask for quick answers.

Fortnite is the last snot anyway.

Thank you for taking the trouble and writing this answer. Now go and help Han blow up the sled.
