try this regex here:
((?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%]).{8,40})
( # Start of group
(?=.*\d) # must contains one digit from 0-9
(?=.*[a-z]) # must contains one lowercase characters
(?=.*[A-Z]) # must contains one uppercase characters
(?=.*[@#$%]) # must contains one special symbols in the list "@#$%"
. # match anything with previous condition checking
{8,40} # length at least 8 characters and maximum of 40
