Can't login/use NordVPN anymore

For days now, I can’t log in to NordVPN anymore. The website gives an SSL error. Using the alternative URLs I can log in (e.g. https://nord-help.com/) but when I open the app, it sends me to https://api-v1.nordvpn.com/v1/users/oauth/login-redirect?attempt=SNIPSNIPSNIP) for logging in which brings up an “PR_END_OF_FILE_ERROR” error. Tried every browser. The browser plugin also doesn’t work anymore, just keeps connecting and then throws an error. Been like that for days - in the UK, provider Virgin Media. Any idea?

Just started getting Login Failed: We hit an authentication error’s. In US though and just started happening last night.

Was having the same issue for the past couple hours until just now when it worked. Logged in through browser, new browser window pops up telling me if I want to open the app now, I closed the program through task manager and then followed through with the browser window and it managed to connect. I attempted this several times over the past hour.
