Re: iOS OpenVPN: Authentication Failed - Data channel cipher negotiation failed (no shared cipher)
Hello. I am having the same issue and I stumbled into and old post which indicates that the iOS client must have a setting changed. Anyone knows what needs to change in either the pfsense firewall itself or in the iOS client? Or maybe I am doing something else that is wrong.

@alfaro I just connected with my iphone, without any issues..
ios 15.6 running 3.3.0 (5047) of the openvpn connect app.. Pfsense running 22.05
I do believe they have gotten rid of the cbc cipher so if you are attempting to use that?
Here are my current server setup..
