Unable to connect while on 3G

Post by PhilPhonic » Mon Jun 22, 2015 6:35 pm

Hi everyone.

I'm hosting my own OpenVPN server and I am unable to connect while I'm using a 3G connection.
This is what my serverlog says while using 3G connection:

The config files (server & client) seem to be "okay", cause it's working while on WiFi.
It also works fine, if I connect from a computer.

Does anyone have an idea what's causing this?
If you need more info (config files, etc), just tell me.

Thanks in advance!

Re: Unable to connect while on 3G

I'm subscribing to a VPN service using OpenVPN Connect on my iPhone and I cannot connect to the VPN server over 3G. Over WiFi it's fine, over 4G works fine, but on a 3G connection it doesn't even seem to try - connect and it immediately shows disconnected.

I've tried with and without Seamless Tunnel and with and without Level 2 Reachability (with Seamless Tunnel) and always the same.

Re: Unable to connect while on 3G

Post by Deimos » Sun Jun 28, 2015 11:35 am

(4th attempts at posting a response of this forum and I really am at the point of giving-up. If you are going to pre-moderate posts then delays of over a week are just daft and you will be driving away a lot of self-help and useful information.)

I have been unable to get OpenVPN to connect over 3G.

Works fine over WiFi and 4G (immediate connect when you manually connect), but when in 3G cover when you manually connect it just immediately flips back to the disconnected state - like it does not even recognise the 3G as a network.

Being rural, I only rarely get 4G coverage and it's all 3G. When in 3G coverage (when OpenVPN refuses to connect - ever), everything else internet based (Safari, Mail, etc.) all work fine.

Sorry about the delays in moderation .. I guess they are all busy ..

As for 3G .. have you tried using TCP protocol for your VPN ?

I switched my server- & client-configs to tcp.

connections on 3G still are not possible.

Re: Unable to connect while on 3G

I am not absolutely sure but your problem sounds like it is similar to this:
https://community.openvpn.net/openvpn/ticket/428

Perhaps you could try disabling --tls-auth ?

Disabling tls-auth worked. But that's not really what I want to do ;-)
So is this a bug in OpenVPN Connect Client?
