Hi Odooers ! Just started the training modules and facing a first problem

Google Calendar Sync just errored with the following output:
" You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy for keeping apps secure."

Error 400 with request details:  redirect_uri=http://ip_adressXXX/google_account/authentication flowName=GeneralOAuthFlow

 
Thanks in advance for your help

Cheers
