[SOLVED] Can't connect to VPN using nm-openvpn

I finally got off my duff and installed -current this weekend. I can't seem to connect to private internet access VPN using nm-openvpn which I had no problem with on 14.2

Am I missing something simple? I've tried PIA's .ovpn files and tried entering info manually. Here's the log

May 2 20:30:49 darkstar nm-openvpn[13182]: DEPRECATED OPTION: --cipher set to 'aes-128-cbc' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM). Future OpenVPN version will ignore --cipher for cipher negotiations. Add 'aes-128-cbc' to --data-ciphers or change --cipher 'aes-128-cbc' to --data-ciphers-fallback 'aes-128-cbc' to silence this warning.

... invalid IP6 config received!
...
... VPN connection: did not receive valid IP config information

Some clues there.

I tried disabling/ignoring IPv6 but ended up with the same error.

Also:

... Network is unreachable

Can you see the internet on this machine?

Yeah, posting here from it. That error confused me, wondered if I needed to be in a certain group or not.

Yeah, your users need to be in the 'netdev' group to use NetworkManager.

Ok, my user is in netdev and I don't know why I didn't try it before but I can successfully connect through openvpn using cli. I did tar my old home directory and extracted into the fresh install. Could some old config be messing with this?

Here's my log that still says network unreachable despite working

If it works at the CLI, then there is an incorrect setting in the GUI.

Yes, absolutely.

Wiped my home directory, no change unfortunately. No luck on searching for similar issue (this thread comes up at the top of results lol). I can live with cli working in the meantime. Will update when I figure out the issue. Thank you for coming to help, I needed someone to bounce ideas with.

you can try downgrading openvpn to 2.4.9 which is the last version in 14.2

Current (pre-release) ChangeLog for x86_64 Tue May 5 20:21:27 UTC 2020 xap/NetworkManager-openvpn-1.8.12-x86_64-1.txz: Added.

networkmanager-openvpn it was rebuilt a couple times.

Were you using slackbuild NetworkManager-openvpn-1.2.10-x86_64-1_SBo in 14.2? You can try that as well.

Not sure what the issue was, but it's working fine now after NetworkManager updates
