repeat the same logs until connect failed.

I get the exactly same error and I don't know why. It works well before today(10/10/2017).

hwdsl2 commented 7 years ago

@durokgit @sherry0319 Hello! The logs indicate that there is some firewall (for example, if you are in China) blocking VPN traffic. Or maybe you did not open the required ports (both UDP 500 and UDP 4500) on your server. This does not look like an issue with the VPN scripts.

You may want to try the following:

  1. Reboot the VPN server, reboot your VPN client, and try connecting again.
  2. Switch to a different VPS server (with a different IP), or try another VPS provider.
  3. Connect using a different VPN client, and/or connect from another network (e.g. 4G instead of Wi-Fi).
  4. Try alternative solutions, such as Shadowsocks or OpenVPN.

i call the server provider to change the IP, that resolve the issue
