Can't Connect to VPN

I just got my TB this morning, am working on configuring it to replace my DInc. I have an L2TP over IPSec (PSK) VPN set up on my DInc, and it works without any problem. I tried the exact same settings on my TB, and I get a box "Attention Unable to connect to the network. Do you want to try again?"
I get this message whether I try to connect from 3g/4g or from my own wireless network (on the same LAN as the VPN). When I look at the logs on the machine hosting the VPN, I see absolutely nothing when I attempt to connect from my TB (connecting from my DInc produces the right log entries). I can also connect to the VPN server from other clients (Windows 7, etc.) without any problems.
*Edit: Cannot connect from TB via PPTP either. Can connect from other PPTP clients.

I have been able to connect to my works VPN (using PPTP) without problem.
Very fast and stable so far! Used it for about 15 minutes without a hitch.

Thanks for the reply. I am still unable to connect directly from my TB, using PPTP or L2TP. If I configure my TB as a mobile hotspot and connect to the internet through it, though, I can connect to my VPN server using the TB's internet connection. But I still cannot connect from the TB using its VPN client.

Lovely. After doing some extensive reading, it sounds like the problem is likely the rom itself. Guess I'll be waiting for an update.

can you list what settings your using in your VPN? since this forum is aout people having trouble and not bragging about whats working?
I too am running dasBAMF and have no VPN's added nor can I find default settings

I'm guessing your post was directed at rajuabju, but hopefully I can help. I do finally have both PPTP and L2TP/IPSec VPN's working on my TB. With what are you having trouble?

Have you tried OpenVPN? I have had the most luck with that, as well as having it forward all traffic through the VPN.

[Q] VPN question

Anyone have any insight into theworkings of VPN on the Z3 (or other Sony products)?
I have a Private VPN setup which connects perfectly with my Nexus 5 and Galaxy Pro 8.4, but using exactly the same settings, I just go from "connecting" straight to "disconnected."
Any ideas?

Not really an idea but I have been using (and still do) Vpn on my Xperia M and the Z3C to connect flawless to some AVM 7490 and 7360 routers. Setting are really exactly the same?

I think the settings are not not the same. The VPN comes directly nativ from Android.

use different config
i mean test both PPTP and L2TP
+ check your session in server side that you connect how many device simultaneously
this is my experience
I can connect pptp vpn on galaxy devices easy and stable But on Xperia l2tp works better!
(actually it doesn't make scene for myself but this what i see!)
:good:

Hhhm, these two I honestly didn't test. My connections (to the above mentioned AVM routers) are of type "IPSec Xauth PSK" which work flawless.

Unfortunately, my router (ASUS), which is my VPN server only has PPTP or OpenVPN options, and is buggy with OpenVPN. So PPTP is my only protocol using this solution.

OpenVPN TCP Connections Fail? LG ROM Fault?

Anyone else experiencing this?
When I try to connect to my VPN server using OpenVPN connect over TCP I get a Network EOF error, and when connecting with the regular Open VPN Client app I get "SIOCGIFHWADDR(lo) failed." Works fine when I connect under UDP, and connecting to the same server under TCP works fine on my other devices (I'm coming from the Nexus 6 2014 and used it extensively on there).
From what I can see on Google it sounds like this is a ROM issue, but wanted to make sure it's happening to everyone so I know it's not just something misconfigured on my end.

I just tried mine and TCP connection isn't working for me either.

Out of curiosity, does UDP work for you? I figured UDP was working, because it showed as connected with no errors on OpenVPN Connect but it actually doesn't load anything from the internet whilst connected and the other OpenVPN app is giving me the same "SIOCGIFHWADDR(lo) failed" error.
This is a pretty major issue

I'll bet your wifi doesn't approve of VPN.
UDP and TCP connection through the Private Internet Access app work fine. There's a configuration problem in what you're trying to do. Either the wifi LAN won't allow it, or your OpenVPN settings are off, or the OpenVPN app is somehow unhappy in Nougat.

It's definitely possible that the OpenVPN settings are off, possibly requiring a different configuration on the v20, however the WIFI is fine and Nougat isn't an issue as it works fine on my Nexus 6 2014 running Android 7.0.

Yep, UDP works without issue through OpenVPN.
My PIA app works as well.

It depends on the security settings with the network, with my home wifi or data using from the Usim, it works ok, if using my company network, it block me out, and won't connect.

Spectrum App Detecting VPN Connection

Hello all,
I setup OpenVPN so I could access my home network and view my TWC Spectrum subscription when out and about . The Spectrum TV app is detecting that im using a VPN and limits what I can watch.
I see in the past users on XDA developers removed blocks from the old app (APK) but im wondering if there's another way to hide the fact I'm using a VPN. I am using the default port (1194) but I'm wondering if changing that will help before I go through and do that.
Thanks.

i had the same problem so i just spoofed the ip on a different time warner cable / spectrum node
and gave me all channels

How does it detect VPN? By outgoing IP or by the settings? Spectrum TV is not the only app. Netflix does the same.

@legendofsounds can you please elaborate on how you got this working?

twc spectrum assigns you an ip address (DHCP) for your subscription so that ip is only going to work for your username and password for the spectrum tv app.
What i did is i logged in to my Netgear r6300 router settings and went to the internet tab i seen my ip address and copied the same numbers shown for
ip: x.x.x.x
subnetmask: 255.255.x.x
defaultgateway: x.x.x.x
i went to visit my family in another city/Node
and logged in to they're router settings and set a static ip with the same ip i had back in my house
once i hit apply settings opened spectrum tv on a roku logged in with my credentials and it worked like a charm.
NOTE: If you try this in the same city where modem A is it wont work because the ip will have a conflict problem

Thanks for clarifying!
This is an interesting work around (and one I'm surprised works).
However, it doesn't help the situation I (and I believe the original poster) are in. I'm able to log into the VPN running on a machine inside my TWC hosted network using my router or even an individual PC, and that works fine. I'm able to see all channels.
Problem is when I'm on my phone using a mobile connection (or wifi on a network that I don't have control over). I can connect to the same VPN on my phone, but the TWC app disallows use when it detects that the phone itself is connected to a VPN. So it seems that we need a way to connect our phones to a VPN without the TWC app knowing it's connected to a VPN.

Is there a working modified apk that disables the VPN check?

VPN connection not working

I have a personal VPN working off of a server in my home. Within the last week or so I've been having problems connecting from my Samsung Galaxy S8 Plus. It just refuses to connect. I rack my brain for over a week trying different settings on the server and nothing seems to change. It is a simple pptp connection. It has been driving me so insane that I actually considered formatting my server and starting from scratch. Then I noticed that if I try to connect from my Galaxy Tab B it connects just fine without any problems. So this seems to be a Galaxy S8 issue. Has anyone else had similar problems? I also have a PIA VPN account, and that seems to connect just fine through their app. On the server side of things it seems to be that I'm getting an error about the LCP sending config request and them timing out
