How to fix Connection failed due to unsupported options in OpenVPN

Honestly, the error message is vague at best. It said there is an unsupported option(s) but didn’t specify which ones.

Anyways, here is the fix.

First, you need to install OpenVPN cli on your computer. On my mac, I installed with Homebrew.

brew install openvpn

After that, I can check the config with the cli:

openvpn --config config.ovpn --verb 4

The output specified which option is not supported:

In simply comment/remove that option from the file and was able to connect to the vpn.


That it’s, folks. Now you know how to fix OpenVPN unable to connect due to some deprecated options.
