How can I resolve Apple Watch sign-in verification issues?

Hey, I got a new iPhone and trying to set up my apple watch anew. I removed it from the account, set it to factory settings and am trying to sign into icloud through the iphone app, just as I am being asked to do.


However, I keep getting this error that says:


"Verification Failed An unknown error occurred".


EVERY TIME.


All those fixed like restarting, checking if the date is set automatically, logging out of WIFi, etc. I have done.


I am very frustrated. Can someone help pls?


Thanks a lot,

Mark

I've been struggling with this problem for a long time, but I found a solution myself


my main apple id account is registered to gmail, there was also a second icloud mail account on my phone, I logged out of icloud mail on my phone and connected an apple account gmail and everything worked!

Me too. I have the same issue. However, when I first pair my iPhone 13 and iwatch s5 I didn’t had the same problem. Along the way my fitness apps stop syncing with my phone so I had my iwatch reset and unpaired only to find out that there is this issue “verification failed, an unknown error occurred” tried it several times. I had no intention to upgrade my watch as still works and does what I need.
