I have OpenVPN Server on Debian 10 for individual purposes. When i connecting to the server from PC, i have internet connection. But from my xiaomi, after tcp connection established, there is no input traffic from the server.

tcpdump on server and openvpn app(visualisated data, idk how can i check it better) showed that packages do not arrive on both sides. On PC and phone there is a one provider. And via free vpn apps from gplay i understood that OpenVPN protocol is not blocked by provider. Configurations below:

server.conf

port 2624
proto tcp
dh none
dev tun
ca keys/ca.crt
cert keys/issued/vpn.crt
key keys/private/vpn.key
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist /etc/openvpn/ipp.txt
push "redirect-gateway def1 bypass-dhcp"
max-clients 5
tls-auth keys/ta.key 0
cipher AES-256-CBC
persist-tun
persist-key
status openvpn–status.log
log openvpn.log
keepalive 5 100
