Unable to add openVPN: login keyring error

Hello team,
I try to configure openVPN but I am failing.
When I load se.ovpn.com.ovpn, create username and password, I click green button “Add”, I receive following error:
The password you use to log in to your computer no longer matches that of your login keyring

I didnt create root account. I am using my account and its password works perfectly, when issuing for example sudo.
I have never changed my password in the past.
It is new installation, 2-3 months old.

Could you advise please ?

feel free to close this topic please. It seems I dont have permission to delete it myself.
