It seems that ever since the 4.0.4 update, my Nexus S cannot connect to my university VPN, flashing an overly broad "Unsuccesful" message whenever I try. The message comes to quickly after initiation to be a username/password problem, and my laptop with Win7 can connect to the same network with the same parameters.
Has anyone else experienced issues when connecting to VPNs?

I am trying to connect using PPTP but I keep getting "Server hung up". Has anyone been able to connect using PPTP? Is there a fix out there to help me connect?
Thanks.
Phone not talking to server
I talked to the IT department and they said that I was connected but the phone does not seem to respond to the server. The server then disconnects after a number of tries to "talk" to the phone and receives no responses.
Recently, i flashed my Rom from wm6.5 to android on htc hd2. However, i encoutered problem with wifi connection at college, which never happened on wm6.5. I could not connect the peap wifi at college even if i typed correct identity and password. it just shows Disconnected. I found a solution that is updating the rom to android 2.3.4 and i did it, it did work at that day. But after that day, I could not connect it again. Any one can help me with it? I think it is not only my problem, cause i found a lot of students in my college cannot connect it on android phone,while it works on iphone.
Asking for some help before I throw my phone out my window. I can't seem to get my SGSII Skyrocket to connect to my VPN which is running on a mac mini server. I have L2TP over IPSec setup which I know works due to that fact that I can connect to it using my iPhone 4 and macbook pro. Unfortunately, I cannot get my Android to connect. All I get is "unable to connect to the network" on the phone itself. When I look at the logs on my server though, it doesn't appear that my phone even tries to establish a connection. Any help would be greatly appreciated. Thanks!
I am able to get a successful VPN connecting using openvpn as well as l2tp. However, after about 5mins of being connected I end up being disconnected. Surely, it is not my provider as I can do use it both PC and other android phones running AOSP. This leads me to believe it is a sense issue. Has anyone else experienced this?
Using Private Internet Access. No issues on this end.
Hello,
I have a galaxy nexus running stock android 4.2.1 with a very peculiar problem. From time to time i have trouble accessing a certain website if i try from wifi or from mobile connection it doesn't matter. If i restart the device the website works without a problem. It was a very odd problem and kept bugging me so i tried to focus on finding the real cause. After a lot of try and error i managed to arrive at this situation:
I have at my disposal 3 different wifi networks (lets call the wifi-1,wifi-2,wifi-3) and mobile broadband connections.
after a reboot of the phone (just to have a clear state) if i connect to wifi-1,2 or mobile conn the website works OK. if i connecto to wifi-3 the site also works OK but then after i disconnect from wifi-3 and connect to any of the other wifi-1,wifi-2 or mobile conn it doesn't work anymore. If i connect to wifi-3 again it works fine on that network.
I've connected to the phone using connectbot and checked the ip address and different params. and i simply can't get a ping to that website. a similar website located in the same subnet but on a different IP still works.
So what could happen on the network layer on the phone to stop working the connection to a certain IP?
Where could i find some info about how to debug IP networking issues on android 4.2.x
PS: I control both the phone and the servers that i'm trying to reach and can't see any traffic coming from the phone on the server.
PS1: I couldn't reproduce the issue with android 4.2.2 only with 4.2.1 (i've also tested android 4.4.4 and couldn't reproduce) i've tested 2 different phones with 4.2.1 and the problem reproduces.
This seems like an issue of handshake and IP Negotiation on the phone. Please see what options you have in terms of DHCP and IPV6 Settings. Please also take a close look at the DHCP Lease time of WiFi-3.
Also Please post in Galaxy Nexus Q&A, Help & Troubleshooting so that the right experts for your device may be of help.
Thank you

IPv6 is disabled
DHCP is similarly configured on all networks. different IP classes. IP addresses change correctly every time. As i'm able to connect to everything i try except that certain website i don't think it's something related with dhcp.
