Do you have the config file which you could post here? I found someone else with that error message who removed the following lines and solved the issue:
Please let us know if that works.
Here's my config as input into the VPN menu for Netduma (certificate info not included):
remote us-seattle.privateinternetaccess.com 1198
"auth-user-pass" looks to be the only exact match, I have "dev tun" not "dev-tun"
I'll delete "auth-user-pass" and investigate "dev tun" vs "dev-tun".
thanks again for the support
I tried removing the "dev tun" first, then "dev tun" and "persist-tun" in separate connect attempts. Neither configs would connect.
I then removed "auth-user-pass" and it connects. Will leave up over night to see if it stays up.
