VPN: Xperia Z don't connect, S3 mini does

[cool_raoul]

Since I had my Z I never been able to connect to my home NAS VPN server using built-in L2TP/IPsec profile.

It stays in "connecting state" for a long time then goes back to "disconnected" state

Today, I had the opportunity to test Samsung Salaxy S3 mini.

Using *exactly* the same settings, i've been able to connect straight away.

How can this be possible?

Any tip to make have my Z connect like the S3?

The only one I've found: replaced my Xperia Z with a Moto X which connects flawlessly to my NAS VPN.

Neither Sony support or any  technicals forums (including this one) has been able to found a better solution unfortunately.

Note: since the flaw has been introduced by a firmware update, you may hope that the upcoming announced Lollipop release will have this fixed.

I too can connect seamlessly with a Moto G.

It's definitely a firmware issue. Also, PPTP seems to work, IPSec doesn't.

We got a test account from another user with this issue and have found the cause of this. It will be fixed in an upcoming software update.

Any update on this, I've just got a xperia Z3+ and the VPN is still broken?

AND IT IS TAGED AS SOLVED ?!?!?!? WHAT IS THIS ....

How can it be possible, that one would buy a Sony supposed to be smartphone, and cant even connect to a L2tp/IpSec VPN for work purposes.

I have a Xperia Z1 and i cant connect to any vpn instance, going from connecting ... Disconnect !
Tried with several other phones with different OS Being common that Android 5.1.1 all of them work from samsung till the funky unbranded chinese phones. Nowadays I have a forsaken Iphone 5 that works a Ipsec tunnel even in china flawelessly and I am doomed to use 2 phones because the outmost incompetence of Sony development team !!
Being more outrageous the amount of time already passed since first post until today .... with the issue still to be solved.

It is clear to everyone in the world that Sony is no longer the company that used to be and nowadays a punny player in the tech market.

My outmost compliments to the useless support team staff that can only reply that some day ... maybe when the phone will already be a dinossaur, that extraordinary bug fix will happen .... What a miserable company that robbed me from my hard working money, with this piece of flawed junk that is an xperia phone. Sony should go back to produce dinassaur stereo devices and old analogical radios and tv s ...

AND IT IS TAGED AS SOLVED ?!?!?!? WHAT IS THIS ....
