What does this red page look like? Does chrome say that the connection is not secure? It should be green here (and it is green for me):
If it is red, then your computer (or your internet provider which is much less likely) is under attack, check C:\Windows\System32\drivers\etc\hosts file (for any entries, by default there should not be any entries except localhost).
Do not attempt to log in from your computer if it is red, find another machine (make sure that the connection is green, i.e. secure, log in and change your password). Or if you have an android phone, download an app and change it from there.
