The "Session Expired" error related to Google reCAPTCHA blocking your login attempt. This can occur for several reasons. This error doesn't occur very often but has been seen by a couple of users. See the below.
Another example is getting caught in an endless captcha images loop. This is another example of Google not being able to verify that you are a real human.
If other users in your office are able to login using their credentials, then this is a local issue for this user.
Typical causes
You are using a VPN or Proxy service
The browser (or extension) may be populating a different password
You may be entering the wrong password or email.
Email is listed as compromised by Google
Password is too weak e.g. "love123"
Email and password have been associated with an existing compromised site(s)
The IP address you are using has been blacklisted or know to have been compromised
Solution
Turn-off any VPN before attempting a login
Clear third party login cookies. (see screenshot below)
Ask us to change your password to be changed to a strong password unique. Use the strong password from now on.
If the above doesn't work
Change your email and password
Use an email that isn't known or is new.
