Hi, 
After 2 days of trying, I got it to work. 
Issue: "THERE IS A PROBLEM"
"one of the fields is missing"

Solutions:

1. "Watch" > "General" > "Software Update"
2. Charge your Apple Watch while trying to pair on your iPhone. Also, try without charging and leaving it to charge for a bit.
3. Change password to only letters and numbers.
4. "Settings" > "Safari" > "Clear History and Website Data".
5. Try throughout the day, but night seems to work more often from anecdotes. (10pm, midnight, 1am, etc.)
