That sucks though. I only experience this after i installed the new update 1.16.210 on my switch. Error still continues even if you tried loggin in successfully through remote connect.
added the screenshot if this helps
I have the same issue. hope this will be fixed. Same error code with mine error code crossbow and error code -2
@magdalena logging in a new account fixed the issue. I just tried it today. After creating another microsoft account then sign in on nintendo switch then immediately signing out and try the old account was what i did.
