OpenVPN Support Forum

I'm currently living in China and have had no problems connecting with the vpn until recently. The connection goes as far as this and then stops working no matter which city I choose:

Can anyone help?

What do you mean by the "city" you choose, and what does your configuration file look like?

I'm going to step out on a limb here and make a few assumptions: It sounds like you're trying to get around the Chinese government's filters by surfing the web through a VPN/proxy server set up in another country. If so, it looks like they've figured out what you're doing, and they're blocking traffic to the domain names / IP addresses of your servers. Otherwise, your servers are down or a firewall is blocking traffic on one end of the connection or the other.

Either way, based on the log excerpt you supplied, it doesn't look like an OpenVPN issue.

hi there,

you can also try using tcp before you give up..
