recurring timeouts during ping

Post by feindler » Fri Nov 04, 2022 2:39 pm

Hi, I have a openvpn server running on Ubuntu server. Only one of the windows clients (via t-mobile in Germany) has issues. It connects but then experiences timeouts.
Server config:
dev tun
proto udp
remote x1.x2.x3.x4 1194
resolv-retry infinite
nobind
persist-key
persist-tun
remote-cert-tls server
auth SHA512
cipher AES-256-CBC
ignore-unknown-option block-outside-dns
block-outside-dns
verb 3

Any suggestions how to overcome this issue?

Hello,

I would suggest to find out if the underlying network connection is the root cause of this first. OpenVPN cannot make the underlying connection 'better'. If the network connection that the OpenVPN tunnel has to go over is bad, then so will the OpenVPN tunnel be. I'd suggest running pings without the VPN connection and seeing if that connection is stable. That has to be the first goal.

Kind regards,
Johan
