OpenVPN Failing

When I try to connect to the openVPN, it says it had a fatal error and couldn’t execute. I had an older Linux version running and it would work on there but today I downloaded the 2020.4 version and now I can’t connect.

What is the error message?

Are you running sudo before you try to open the OpenVPN (Kali 2020 has decided you need to run sudo a lot before you can do anything usefull, when the old versions were a bit more permissive)

Hi, I dont know if is the same problem but I’m getting error from today with OpenVPN… I’ve Tried to download again the vpn pack and Im still get the same error.> @TazWake said:

First question - are you running this as sudo / su or root?

i have the same issue, im not running as root and when i typed sudo mohan10216.opvn it just keeps on saying an error

If that’s the full command you’re running it won’t do anything.

“Sudo openvpn FILE”

Use the full command
“sudo openvpn your_vpn_file”

I’ve tried udp/tcp files with sudo full command, nothing works. It happened after kali update.

Where should I check or configure?

Has anyone fixed this yet…I’m having the same issue trying to connect to HTB VPN. I’ve tried all UDP and TCP file and ran them as sudo.

Sometimes you have to try more casual things like redownloading the vpn file, changing server or wait a few minutes before trynig again

Worked in my case. Tried all sorts of OpenVPN and Linux stuff and saw this and decided to try TCP instead of UDP and using a new server - and it worked.
