Cannot connect to the real [website.com] I just bought a Galaxy Tab 4 and I'm trying to set it up for development.

Being behind a proxy that needs authentification, I installed drony to provide my credentials. I'm now able to surf most http websites and few secure https websites.

On the other hand, I can't get most https sites and all the google services (Play, Maps, Youtube) to work. 

I tried to use the google.com website to connect to my google account, and I got a page with the following error message :  "Something is currently interfering with your secure connection to [site].
Try to reload this page in a few minutes or after switching to a new network. If you have recently connected to a new Wi-Fi network, finish logging in before reloading.

If you were to visit [site] right now, you might share private information with an attacker. To protect your privacy, Chrome will not load the page until it can establish a secure connection to the real [site]. "

Can somebody help?
I finally got it to work! 

google.com (and other websites) refuse requests from hosts that doesn't have the date properly set on their device. 
At the first startup, I didn't bother setting the date on my tablet (on iOS it sets automatically). 

After manually  setting the tablet's date and time, the error page is gone and I have access to all the google apps.

EDIT.
According to Izzy, it was Chrome itself that refused the connection, possibly because the certificate dates were not matching.
