After upgrading/installing vCenter Server 6.7.0d 9451876 unable to login onto VAMI page, but able to login using putty on VCSA using same root password.

This is known issue, if we are having any special characters such as : or . (colon or dot) in the password.

Workaround is to reset the password which doesn’t contain these characters.

And it has been fixed in 6.7u2 which is expected to be released in Q4 2018.
