Unable to connect to NAS VPN Server via Network Preferences

[kcwjr]

Previous to Big Sur Beta 4, I was able to connect to my NAS VPN Server via Network Preferences VPN profile. It had worked continuously for almost two years. However, after the Beta 4 upgrade(?), anytime I try to connect I get "The L2TP-VPN server did not respond." error. I have another mac that is running Catalina and using the same VPN profile and is able to connect. I have a third party app, Tunnelblick, on the imac that can't connect which is able to connect . I have restarted the mac, the server, reset the profiles to a no avail. Sure does appear to me that there is a bug in the network preferences in Big Sur. I have posted same issue in the Feedback Assistant on the Apple Developer website as well. Any suggestions from anyone. Thanks.

I got this issue after tonights beta 8 update. I am connecting to a Cisco VPN though. This is critical for me, since I cannot do some of my work without that VPN... 😝

Did you ever solve your situation?

 

[kcwjr]

Yes, I deleted the VPN setup in System Preferences and recreated it. That worked.

Thanks. Didn't help here though...

It just tries to connect, and after a minute or so it stops trying. No matter what login credentials I give it, or if I delete and recreate the VPN settings.

Very frustrating.

For me PB8 fixed an issue I was having with Cisco VPN (resolving hostnames hit/miss between reconnects), now it's working consistently

business VPN is not working for me either today after latest public beta update

VPN used to pop up the username/password dialog but it doesn't do that after PB8. I tried putting my password in the settings but it failed to connect. Had to restore to Catalina.
