Google has some fussy secure access restrictions. If your application is not compliant then you need to explicitly tell Google to relax the checks.

See https://support.google.com/accounts/answer/6010255?hl=en or https://support.google.com/a/answer/6260879?hl=en 

The link to relax the checks can be found here.
