Fixed: Hesk Email Settings: smtp.gmail.com error

I was setting up Hesk Server and having trouble getting the email to work with the below setup

Server: smtp.gmail.com
Port: 587
SSL: OFF
TLS: ON

I got this error below even though I type my correct password:

534-5.7.14 <https://accounts.google.com/signin/continue?

SOLUTION:

1. Open this link https://accounts.google.com/DisplayUnlockCaptcha

2. Enter you gmail credential if ask.

3. Click Continue.

4. Go back to HESK email settings and to setup again.
