Android studio proxy settings - android-studio

Question

I'm using ubuntu 16 and I downloaded and installed the last version of android-studio (file android-studio-ide-181.5056338-linux.zip).
I'm running android-studio behind a corporate proxy. I unzipped the file and I launched the studio.sh and I configured the proxy by following these links https://developer.android.com/studio/intro/studio-config#proxy and link https://www.jetbrains.com/help/idea/2018.1/settings-http-proxy.html
Note I configured also my proxy authentication (both username and password) as showed in this image:
When I check the connection if I use some unsecure URLs (e.g. http://www.google.it) all works pretty good; the check is OK. If I use secure URLs (e.g. https://www.google.it) I get a 407 error (authentication required)
as showed in this image
Then I saved the settings and closed the IDE. Note I created no project yet... I just installed the IDE.
Now every time I start the IDE in the idea.log I see the following error:

So it seems that my proxy settings are not used by the update phase. Note i tried also to use unsecure connections but the error remains.
Ho can I solve this issue?
Thank you

Try this.
Change your Proxy settings like this.
And test your connection again.
