Apple Watch 6 Cannot Connect to Wi-Fi (always said incorrect password)

Hey guys, anyone encountered the same trouble after updating to watchOs10? I have no issue, especially specific to this one since bought my AW6... Got this issue after the update and seems cannot connect my AW to my home wi-fi. I've tried to hard restart my watch, phone, unpair, even changing the password for the router as well. I've inputted the password manually and from the "share wi-fi password" feature from the iphone, to no avail.

I need to clarify that the wi-fi works just fine with the iphone. The only issue I have is with the apple watch. Anyone has any particular solution, or having this same issue(s) with me as well?

Any feedback is thoroughly appreciated. Thank you.
