Yeah remove your existing image. then go click add container on the docker page.
click on the template and go down to your user templates...
Then click on the openvpn one.
Then go to the repository line and change it to linuxserver/openvpn-as:2.6.1-ls11 .
That is literally all I had to do.
This is why I love the unraid community. I wait to upgrade, and my issues are already addressed in the forums when I do. This fixed it for me.
Thanks, @aptalca❤️
