Connect to a VPN on android using OpenVPN.

[Wallesss]

Hello, I can't connect to a VPN on a Huawei tablet using the OpenVPN configuration file from VPNGate (see the file "vpngate_vpn361297839.opengw.net_tcp_443.txt"). However, if I use the configuration file obtained on the VPNBook website, the connection is successful (see the file "vpnbook-fr231-tcp80.txt"). In the file "debugVPN.txt" the connection error log is attached.

Why can't I connect to the VPN server using any OpenVPN configuration files from your site?

Modify this in vpngate_vpn361297839.opengw.net_tcp_443

Code: Select all

#cipher AES-128-CBC
data-ciphers AES-128-CBC
auth SHA1

solo, why did you block another topic? I have a new error with another ovpn file.

Code: Select all

Note: --cipher is not set. OpenVPN versions before 2.5 defaulted to BF-CBC as fallback when cipher negotiation failed in this case. If you need this fallback please add '--data-ciphers-fallback BF-CBC' to your configuration and/or add BF-CBC to --data-ciphers.

*I have already added a string with the AES-128 encryption algorithm to the source file.

Code: Select all

data-ciphers AES-128-CBC
auth SHA1

OK, you have a point. Here is a new Android workaround.

cipher AES-128-CBC
data-ciphers AES-128-CBC
auth SHA1

Works for me.

1) It works for me. But the connection breaks with an interval of 1 second.
2) Where did you get the IP address 123.195.133.10? It was missing from the original file.

[solo]

- it's very stable on my Android 12 (your Android 7 is ancient)
- on https://www.vpngate.net/en/ search for 123.195.133.10 and click the OpenVPN Config file link.

EDIT

Constant reconnecting is caused by governments' VPN blocking, eg. viewtopic.php?f=7&p=102477
