Hello,
I followed a tutorial to setup the community version of openvpn on my ubuntu 18.04 server:
https://linuxconfig.org/openvpn-setup-on-ubuntu-18-04-bionic-beaver-linux#h7-step-2-server-infrastructure-setup
I created 2 client configs: one for my computer (Windows 10) and one for my mobile phone (Samsung S20). On the computer, it works well but on the phone, the connection seems to work but I can't load any web page and the bandwith is about few Bytes/s (upload and download).
Here is my server config:
port 1194
proto udp
dev tun
ca ca.crt
cert server.crt
key server.key # This file should be kept secret
dh dh2048.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist /var/log/openvpn/ipp.txt
push "redirect-gateway def1 bypass-dhcp"
keepalive 10 120
tls-auth ta.key 0 # This file is secret
cipher AES-256-CBC
persist-key
persist-tun
status /var/log/openvpn/openvpn-status.log
verb 3
explicit-exit-notify 1
The ovpn client file:
client
dev tun
proto udp
remote XXXX 1194
resolv-retry infinite
nobind
user nobody
group nogroup
persist-key
persist-tun
<ca>
...
</ca>
<cert>
...
</cert>
<key>
...
</key>
remote-cert-tls server
key-direction 1
<tls-auth>
...
</tls-auth>
cipher AES-256-CBC
verb 3
And the Android logs:

What is wrong for the connection on the Android phone? How can I solve that?
Thank you for your help
