SUMMARY
the importation of ovpn fails in system settings/connections does not work correctly. while importing the ovpn file, I am getting an error configuration error: unsupported blob/xml element(line xx) . following this post https://askubuntu.com/a/1179494 I succesfully imported after removing the `<connection>` and `</connection>` (the line xx was exactly for the <connection>. then I proceed to add my user name and password and changed store password for this user to store password for all users. up to this everything worked. the openvpn icon apeared in the wifi/ethernet applet, and I could 'connect' to it. when I connect to it, I lost internet, i can not acces any page at all.
the thing is that the ovpn (original one) works correctly (i have internet AND access to the pages that the vpn gives me acces to) as if I run in the terminal `sudo openvpn --config configFile.ovpn` this works correctly

STEPS TO REPRODUCE
1. go to system settings/connection/ import vpn from file
2. modify ovpn file to remove the problematic lines
3. succesfully import it
4. add user name and password
5. try to connect to vpn

OBSERVED RESULT
kde 'succesfully' connects to the vpn but I dont have anymore internet

EXPECTED RESULT
be able to connect to internet thought the vpn
