I have a similar issue, but my sailfish os beta's version is up to date (Sailfish 184.108.40.206).
I've tried to connect different networks (different routers and different ssecurity), and it seems that its works only with the unsecured open network.
But before I downloaded the update i could connect to my workplace's wifi (WPA2-PSK secured)
Now when i'm clicking to a password protected network for connecting, it prints immediately the sorry error message, and dont asking for the password...
Am I doing something wrong?
