Your ISP might be blocking OpenVPN and/or high ports. Does this apply to all other labs you’re trying to connect to?

The only workaround I can think of (and try this at your own discretion) is to chain your VPN connection through a 3rd-party VPN. The problem with this, however, is that you’re might have a hard time with DNS resolution conflicts (between the 3rd-party VPN and the lab’s). If DNS is not an issue, that method should work, but you’re gonna have to deal with potential latency.

3

check if your endpoint security (Antivirus sw/firewall) is not blocking any related traffic.
Also make sure you are using OpenVPN2.x version. version 3.x doesn’t support TAP.

4

try commenting out the “remote… udp” line and check if it works over tcp

Doubt that’s gonna work as per the quoted logs. It’s most likely an ISP-related issue; I’ve been battling the same issue, and that’s why I know it’s very likely theirs is the same. Could also be a firewall config if one’s installed.

yeah I missed that one, sorry

No need to apologize, mate—you’ve been doing a great job on the forums. Keep up the great work! :slight_smile:
