I've followed this great tutorial to create my own OpenVPN server => https://www.digitalocean.com/community/tutorials/how-to-set-up-an-openvpn-server-on-ubuntu-18-04
I've generated a client1.ovpn file in which ca.crt, client1.cert, client1.key and ta.key are embeded but when I import this file in my OpenVPN connect Version 3.0.1.(770) I got this error :
Code: Select all
Failed to import profile
Failed to import OVPN profile from selected file. Missing/bad files : ca.crt, client.crt, client.key

I tried on 3 devices :
- IPhone 5S version 10.3.1 (14E304) / OpenVPN version 3.0.1.(770) <=== doesn't work
- IPad Air version 12.0 (16A366) / / OpenVPN 3.0.1 <=== doesn't work
- Ubuntu 18.04 computer <==== Work perfectly
Because it works with the same .ovpn file on my ubuntu compter and not on iOS devices I think it's a bug of the iOS App. Can you confirm it ? Is there a solution ?
Thanks !
EDIT
I just tried on a Samsung Galaxy S7 with OpenVPN connect v3.0.5 and got the exact same error ...
