1671115 - VPN BER issues

Status: RESOLVED INVALID

I have a VPN config from https://login.mozilla.com/openvpn
When I visit a website that requires 2FA (like the link above), I get instant push notifications to my mobile through duo
Connections to the Berlin VPN (openvpn.ber3.mozilla.com) worked flawlessly for the last couple of months

My issue:
Whenever I try to establish a connection to the VPN, I do not get a push notification and the authentication times out.

My attempts to remediate / analyze
I tried unlocking my phone and making sure to refresh duo (swipe down), in case this is an issue on my end, but I also verified that duo in itself is working correctly (see point 2 above).
After waiting a couple of minutes, I do get a duo push notification from the VPN, but that's well after the timeout.
Yesterday, I retried a couple of times and at some points the push notification came swiftly enough that my vpn client didn't time out. But it's been tricky again this morning.

Let me know if there's any other info I can provide.

Works perfectly with VPN-US.
