OpenVPN 2.6 is not compatible with all appliances (like PFSense). So there should be an option to switch back to the older version.

Hi tux84,

Viscosity 1.11 provides a new compatibility setting that will allow it to connect to servers running legacy versions of OpenVPN. Please run through the steps listed in the following article, which should get you connecting again:

Is there a way to revert back to the prior version? I cannot connect at all. This should have clearly conveyed prior to an update especially when there are breaking changes. Is there a link to the prior version?

Forget. All settings were wiped. Not worth it.

Just in case someone has an issue connecting: The key-size parameter is deprecated. So just open up the connection settings > advanced and there delete the key-size parameter.

removing this from the Connection config's "Advanced" fixed it for us (using pfSense latest as OpenVPN server)
Code: Select all
ncp-disable
Hope it helps someone!

P.S. We are opening a ticket with Netgate support, too. so that they are aware
