Android 4.3 - No internet access, unable to connect to the proxy server error My Lg nexus 4, received the android 4.3 update last night. I didn't do much on it, opting to sleep peacefully knowing that I had the latest and greatest in android software, but this morning I noticed that I cannot access the internet either via the web browser or the play market.

Chrome complains "unable to connect to the proxy server" regardless of what site I try to go to. And the play store says "No connection".

However, I do have a connection, I can use gmail to send and receive messages and I can use whatsapp and twitter and a few other apps.

I have checked the network settings for both my 3G and wifi, and there are no proxy settings or anything enabled.

Does anyone know what the problem might be?

EDIT:

Does this happen on both WiFi and mobile data? YES

What apps have trouble, and which do work? Chrome and the play store as far as I can see are both troublesome. Other apps work i.e. my whatsapp can send/receive messages, twitter works and so on.

What's the color of your signal bars in the notification area? Blue, full signal on HSDPA.

EDIT 2:
I think this may be affected by some setting left over from a rogue app. I have played with VPN apps and proxy setting apps in the past (a few months ago) so perhaps the new 4.3 update read some of those settings and configured things incorrectly?
If you have cleared your Google Service Framework data to receive the update, it will change your device ID that Google uses to recognise your device. This also affects the tokens used by some apps (i.e. Google Now, Google Search, Chrome) and they won't connect to the Google servers properly and refuse to work for a while (this was like 24~48 hours for me, before these apps started behaving as the tokens were eventually refreshed). Other non-Google apps will continue working.

More details of why this happens can be found in this reddit post by a Google engineer:
