Bug 401325

This is weird, I have never experienced such behaviour. Can you open a terminal and run "export QT_LOGGING_RULES=plasma-nm*.debug=true" and from the same terminal session restart kded5 to see output from it? Then try to reproduce this issue.

What type of VPN do you use? Do you have password for this VPN saved?

It's openVPN (ProtonVPN). Yes, password is saved but unencrypted, I dont have to enter any password when connecting (the VPN one or mine).

So your password is stored for all users, is that correct? You don't use KWallet, right? If so, it looks like a NetworkManager is responsible for this. NM asks our secret agent to remove the secrets from unknown reason.

Maybe try to report your problem here: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/issues

Yes, the password is stored for all users, so I guess I dont use Kwallet? (it's installed though). Reported here: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/issues/84

Closing, it's an issue in NetworkManager.
