I'm not sure where my last post went. I ended up doing a clean install to get everything working again.

I tried reaching out to Nord VPN to troubleshoot before I did that but it was after hours. I needed my laptop to I just did a clean install.

Issue resolved (ish). Kinda upset.

Did you ever try the advice about creating a new Location?

Failing that, go ahead and post the Etrecheck report.

Early on, I deleted all 'remembered' locations. Later, I deleted Wifi, restarted and readded wifi. If readding Wifi is adding a new location, then yes, I've done that.

I'm checking on EtreCheck now.

There seems to be a VPN in play here, based on NEIKEv2Provider.

There’s also some WebKit or Safari bits that are busy.

And in general, remove Flash, unless you really need that.

Ah, thanks. Should probably add “VPN clients” to the usual litany of add-on stuff that breaks other stuff.
