iOS: Cannot connect to server

[ypo777]

I have Wireguard VPN setup on Ubuntu 20.04 (LTS) x64 [DigitalOcean Server]. I used QR to add tunnel to my phone. But no internet when I check logs on my phone it fails to handshake with server.

" 2021-05-04 18:23:34.150 [NET] peer(sJ2L…VggQ) - Sending handshake initiation 2021-05-04 18:23:39.402 [NET] peer(sJ2L…VggQ) - Handshake did not complete after 5 seconds, retrying (try 19)"

This is client conf: [Interface] PrivateKey = Private Address = 10.104.0.6/32,fd42:42:42::6/128 DNS = 94.140.14.14,94.140.15.15

[Peer] PublicKey = Public PresharedKey = PreshareKey Endpoint = server_ip:57733 AllowedIPs = 0.0.0.0/0,::/0

This is server conf(wg0.conf): `[Interface] Address = 10.104.0.4/24/24,fd42:42:42::1/64 ListenPort = 57733 PrivateKey = Private PostUp = iptables -A FORWARD -i eth0 -o wg0 -j ACCEPT; iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE; ip6tables -A FORWARD -i wg0 -j ACCEPT; ip6tables -t nat -A POSTROUTING -o eth0 -j MASQUERADE PostDown = iptables -D FORWARD -i eth0 -o wg0 -j ACCEPT; iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE; ip6tables -D FORWARD -i wg0 -j ACCEPT; ip6tables -t nat -D POSTROUTING -o eth0 -j MASQUERADE

Client test

I'm from Myanmar where military coup is happening. ISPs are blocking some internet services I do not know that is the reason? or My server configurations ? I can't access digital ocean without using vpn.

If he can connect to the server with ssh, chances are you're not being blocked. I'd check with IPTables or maybe some other firewall. netstat -nl iptables -L
